RESUMEN

OBJECTIVES: To study the results of chemotherapy combined with intravesical hyperthermia in patients with mainly BCG-failing carcinoma in situ (CIS). METHODS: Patients with histologically confirmed CIS were included retrospectively. Outpatient thermochemotherapy treatment was done with mitomycin-C (MMC) and the Synergo system SB-TS 101 (temperature range between 41 and 44 degrees C), weekly for 6-8 weeks, followed by 4-6 sessions every 6-8 weeks. RESULTS: Fifty-one patients were treated between 1997 and 2005 from 15 European centers. Thirty-four were pre-treated with BCG. Mean age was 69.9 years. Twenty-four patients had concomitant papillary tumors. The mean number of hyperthermia/MMC treatments per patient was 10.0. Of the 49 evaluable patients 45 had a biopsy and cytology proven complete response. In two patients CIS disappeared, but they had persistent papillary tumors. Follow-up of 45 complete responders showed 22 recurrences after a mean of 27 months (median 22): T2 (4), T1 (4), T1/CIS (1), CIS (5), Ta/CIS (2), Ta (5) and Tx (1). Side effects (bladder complaints) were generally mild and transient. CONCLUSIONS: In patients with primary or BCG-failing CIS, treatment with intravesical hyperthermia and MMC appears a safe and effective treatment. The initial complete response rate is 92%, which remains approximately 50% after 2 years.

RESUMEN

The traditional anatomical description of the seminal vesicles is based on autopsy and imaging studies. Trans-peritoneal robotic-assisted laproscopic surgery, with its three-dimensional magnified view and miniature articulated working instruments, provides an opportunity to perform accurate dissections of the seminal vesicles even when extremely long and tortuous. We used specimens obtained by robotic-assisted laparoscopic radical prostatectomy (RLRP) for accurate anatomic assessment of the dimensions of the seminal vesicles. Digital photos of 78 specimens from men (mean age 59 ± 6.1 years) who underwent RLRP were analyzed using the Image Pro Plus software. Seminal vesicle dimensions were correlated with patients' age, weight, height, prostate weight, sexual function profile (SHIM) and symptom severity score of the lower urinary tract symptoms (IPSS). We found that the length of the seminal vesicles is highly variable (range of 8.5-94.6 mm). The average seminal vesicle length was 31 ± 10.3 mm and its average volume 7.1 ± 5.2 ml. The right seminal vesicle was significantly larger than the left in length, width and volume (P < 0.003). The seminal vesicles were found to be highly asymmetric with a mean difference of 17.8% in length and 24.9% in width between the sides. No correlation between seminal vesicle dimensions and any of the parameters tested was found. We concluded that the normal human seminal vesicles are characterized by marked (11-fold) variation in length and are asymmetric in most patients. The right seminal vesicle is significantly larger than the left. Seminal vesicle dimensions cannot be predicted from other morphometric or physiologic parameters.

RESUMEN

PURPOSE: Erectile dysfunction (ED) is a common sequel of pelvic fracture urethral disruption (PFUD). After repair of the urethral injury ED may be the most devastating long-term effect for the patient. Some patients with ED may regain normal erectile function. We prospectively studied the response to sildenafil and the erectile function of patients with ED due to PFUD. MATERIALS AND METHODS: The erectile function of patients referred to us with PFUD for urethroplasty were prospectively evaluated before surgery. Patients underwent nocturnal penile tumescence testing and, if results were abnormal, penile duplex ultrasonography with intracavernous injection and arteriography were performed to diagnose the etiology of ED. Patients were questioned about erectile function every 3 months after surgery and if they complained of ED they were offered 100 mg sildenafil. Patients were followed for at least 18 months after surgery. RESULTS: A total of 29 consecutive patients were evaluated and 22 (76%) of them had ED before surgery. Sufficient followup was available for 15 of the patients. Overall 47% of these patients responded favorably to sildenafil. Of the patients 60% with neurogenic ED and 20% of those with arterial ED responded to this treatment. In 33% of the patients ED resolved within the followup period. All patients with spontaneous resolution of ED previously responded to sildenafil (71% of sildenafil responders). CONCLUSIONS: In patients with ED due to PFUD, those with neurogenic ED are more likely to respond to sildenafil than those with arterial damage. Favorable response to sildenafil may predict spontaneous resumption of normal erectile function over time.

RESUMEN

INTRODUCTION: Superficial bladder cancer can be treated by transurethral resection (TUR) and adjuvant intravesical therapy. Intravesical bacillus Calmette-Guérin (BCG) has been proven to be more efficacious with respect to recurrence prevention than intravesical chemotherapy, although at the cost of more severe side effects. There is a need for a new treatment modality with higher efficacy and less toxicity. The subject of this study is the efficacy of local microwave hyperthermia and chemotherapy treatment in intermediate or high risk superficial transitional cell carcinoma (TCC) of the bladder. PATIENTS AND METHODS: Ninety eligible patients received adjuvant treatment with a combination of mitomycin-C (MMC) and local microwave hyperthermia. All patients had multiple or recurrent Ta or T1 TCC of the bladder and were classified as intermediate or high risk according to EAU criteria. In total, 41 patients were BCG failures. The treatment regimen included 6 to 8 weekly sessions followed by 4 to 6 monthly sessions. Follow-up consisted of video-cystoscopy and urine cytology every 3 months. All patients were observed for 2 years. RESULTS: Kaplan-Meier analyses of the total group (N = 90) indicated that 1 year after treatment only 14.3% (SE 4.5%) of all patients experienced a recurrence. After 2 years of follow-up the risk of recurrence was 24.6% (SE 5.9%). No progression in stage and grade was observed. CONCLUSION: Microwave induced hyperthermia combined with MMC has promising value in intermediate or high risk superficial bladder cancer patients compared to literature data of BCG and/or intravesical chemotherapy, particularly where other treatments, i.e. BCG, have failed.

RESUMEN

OBJECTIVES: To evaluate the effectiveness of combined local bladder hyperthermia and intravesical chemotherapy for the treatment of patients with high-grade (G3) superficial bladder cancer. METHODS: Patients with G3 bladder tumors (Stage Ta or T1) were treated with combined intravesical chemotherapy with mitomycin-C and local radiofrequency hyperthermia of the bladder wall. The patients were treated with either a prophylactic protocol (40 mg mitomycin-C) after complete transurethral resection of all tumors or with an ablative protocol (80 mg mitomycin-C) when visible tumor was seen on video-cystoscopy or bladder biopsies were positive for carcinoma in situ. RESULTS: Combined chemo-thermotherapy was administered to 52 patients with high-grade superficial bladder cancer (40 patients with Stage T1 tumor, 11 with Ta, and 3 with concomitant or isolated carcinoma in situ). At a median follow-up of 15.2 months (mean 23, range 6 to 90), no stage progression to T2 or disease-related mortality had occurred. The bladder preservation rate was 86.5%. The prophylactic protocol was administered to 24 patients. After a mean follow-up of 35.3 months, 15 patients (62.5%) were recurrence free. The bladder preservation rate was 95.8%. The ablative protocol was administered to 28 patients. Complete ablation of the tumor was accomplished in 21 patients (75%). After a mean follow-up of 20 months, 80.9% of these patients were recurrence free. The bladder preservation rate for the ablative group was 78.6%. CONCLUSIONS: Combined local bladder hyperthermia and intravesical chemotherapy has a beneficial prophylactic effect in patients with G3 superficial bladder cancer. Ablation of high-grade bladder tumors is feasible, achieving a complete response in about three quarters of the patients.

RESUMEN

OBJECTIVES: To report the treatment of patients who presented with vesico-ureteric stricture after kidney transplantation, using a minimally invasive endourological approach. PATIENTS AND METHODS: Patients (10 men and four women, mean age 34 years, range 22-55) were assessed at presentation by serum creatinine level, ultrasonography and intravenous pyelography when the serum creatinine level was < 200 micromol/L. When there was hydronephrosis of the allograft a percutaneous antegrade pyelogram was taken, followed by inserting a nephrostomy. After decompression a stent nephrostomy was passed into the bladder and the strictures at the vesico-ureteric junction incised along the stent during cystoscopy. RESULTS: All 14 patients were treated endourologically by an endoscopic incision through the bladder; 13 fared well and one died from sepsis and transplantation problems. The mean follow-up was 8 months. CONCLUSIONS: Simple incision of the stricture via cystoscopy was safe and effective, and succeeded in most patients. The endourological management of ureteric lesions is feasible and is currently our first-line management of ureteric complications after kidney transplantation.

RESUMEN

PURPOSE: Erectile dysfunction is a common sequel of pelvic fractures, particularly those associated with posterior urethral injury when it can be neurogenic or arteriogenic due to damage to the cavernous nerves or branches of the pudendal arteries. We studied erectile function of patients with posterior urethral injuries due to pelvic fractures. MATERIALS AND METHODS: Patients referred for posterior urethral reconstruction and strictures due to pelvic fractures were evaluated before reconstruction. All patients underwent nocturnal penile tumescence testing, and if those results were abnormal, penile duplex ultrasound with intracavernous injection was performed. Patients with normal vascular function on duplex ultrasound were diagnosed with neurogenic erectile dysfunction. Those patients with abnormal arterial function on duplex ultrasound underwent arteriography to further define the extent and location of arterial damage. RESULTS: The study included 25 consecutive patients with posterior urethral strictures and a mean age of 28.6 years. Of the patients 18 (72%) had erectile dysfunction as demonstrated by nocturnal penile tumescence and all underwent penile duplex ultrasound. Ultrasound confirmed normal vascular response in 13 of the 18 patients and they were diagnosed with probable neurogenic erectile dysfunction. The remaining 5 patients (28%) with erectile dysfunction had an abnormal arterial response, and significant arterial pathology was confirmed by arteriography. CONCLUSIONS: Erectile dysfunction is common in patients with pelvic fractures associated with urethral injury. We believe that erectile function should be assessed and documented in such patients before attempting urethroplasty. In the majority of these patients erectile dysfunction is caused by disruption of the cavernous nerves with sparing of arterial inflow.

RESUMEN

PURPOSE: We determined whether the thin ureter of the young child transports stone fragments after extracorporeal shockwave lithotripsy (ESWL) as efficiently as the adult ureter does. This determination was done by comparing the outcome after lithotripsy of renal stones greater than 10 mm. between young children and adults. MATERIALS AND METHODS: Our study group consisted of 38 children 6 months to 6 years old (median 3 years) with renal stones greater than 10 mm. in diameter. This group was further divided into 3 subgroups according to the longest stone diameter on plain abdominal film. There were 21 children with a renal stone diameter of 10 to 15 mm. (subgroup 1), 8, 16 to 20 mm. (subgroup 2) and 9 greater than 20 mm. (subgroup 3). The control group consisted of 38 adults older than 20 years randomly selected from the local ESWL registry. Each adult was matched with a child regarding stone diameter and localization. The control group was similarly divided into subgroups 1a, 2a and 3a. ESWL was performed with the unmodified Dornier HM-3 lithotriptor (Dornier Medical Systems, Inc., Marietta, Georgia). The stone-free rate, complication rate, and need for tubes, including stent or nephrostomy, and greater than 1 ESWL session were compared. RESULTS: The stone-free rate was 95% in the study and 78.9% in the control group (p = 0.086). Stone-free rates were 95%, 100% and 89% in subgroups 1, 2 and 3, and 95%, 65% and 56% in subgroups 1a, 2a and 3a, respectively. There were 10 children and 4 adults who underwent greater than 1 ESWL session (p = 0.14). Then there were 10 children and 6 adults who required a tube before ESWL (p = 0.04), and almost all of them were included in subgroups 3 and 3a. Early complications were rare in both the study and control groups. Late complications had included 2 cases of Steinstrasse in the control and none in the study group. CONCLUSIONS: The stone-free rate after ESWL for large renal stones is higher in young children compared to adults with matching stone size. Renal stones greater than 20 mm. often require more than 1 ESWL session. The pediatric ureter is at least as efficient as the adult for transporting stone fragments after ESWL.

RESUMEN

OBJECTIVE: We evaluated the tumor recurrence pattern after radical or nephron-sparing surgery for localized renal cell carcinoma. Based on this pattern, we suggest a surveillance protocol after surgery. METHODS: The outcome of 200 consecutive patients with localized renal cell carcinoma (RCC) that were operated on between January 1982 and December 1997 was evaluated retrospectively. Radical nephrectomy was performed in 155 patients (77.5%), and nephron-sparing surgery in 45 patients (22.5%). The timing and site of disease recurrence were correlated with parameters of the primary tumor. RESULTS: One hundred and twenty-four patients (62%) had pathological stage T1, 26 (13%) had stage T2, and 50 (25%) had stage T3 (41 stage T3a, 8 stage T3b, and 1 stage T3c). The mean follow-up was 47 months (range 6--169 months). Four patients (3.2%) with stage T1, 6 patients (23%) with T2, and 13 patients (26%) with T3 developed recurrent disease. None of the patients with a stage T1 tumor, smaller than 4 cm, had tumor recurrence. There were no recurrences after nephron-sparing surgery compared to 23 recurrences (14.8%) among patients after radical nephrectomy (p = 0.01). Only 1 patient who underwent pulmonary lobectomy for asymptomatic metastases smaller than 2.5 cm, found by routine chest CT, attained long-term survival. CONCLUSIONS: The prognosis of patients after radical nephrectomy for renal cell carcinoma, smaller than 4 cm, is excellent and they do not need radiological follow-up. Patients with larger T1 tumors, 4--7 cm in diameter, or a higher stage should be followed with CT of the chest and abdomen done every 6 months for 5 years and then annually. Following partial nephrectomy of small renal tumors periodic renal ultrasonography should be done to rule out local recurrence in the operated kidney.

RESUMEN

BACKGROUND: Despite years of research and clinical experience with acute appendicitis, the rate of complications in the pediatric age group continues to be high. OBJECTIVE: To characterize the profile of the child with appendicitis complicated by perforation or intraabdominal abscess. METHODS: Between 1 January 1985 and 31 December 1997 in our department, 581 children under the age of 14 years were clinically diagnosed as suffering from "acute appendicitis." The final diagnoses were: while appendix in 28 cases (4.8%), acute non-complicated appendicitis in 472 (81%), and complicated appendicitis in 81 (13.9%), including 51 cases of free perforation (8.7%) and 30 cases of intraabdominal abscess (5.2%). We retrospectively reviewed the charts of all children with complicated appendicitis and those of 70 randomly selected children with non-complicated appendicitis, and compared patient age, gender, weight percentile, past medical history, and course of the illness. RESULTS: The children with complicated appendicitis were significantly younger (P = 4.8 x 10(-7)), they had higher oral and rectal temperatures (P = 7.9 x 10(-8)), higher platelet count (P = 0.0008) and lower hemoglobin level (P = 0.004). No difference was found in white blood count (P = 0.41). Total delay from symptom onset to surgery was 33 hours (SD 23) in the non-complicated group, 60 hours (SD 38) in the perforated appendicitis group, and 176 hours (SD 107) in the intraabdominal abscess group (P = 4.6 x 10(-8)). No difference in intra-hospital delay was found. CONCLUSIONS: Children with complicated appendicitis are characterized by younger age, longer delay from symptom onset to correct diagnosis, and typical laboratory findings. Delays in diagnosis can be avoided by first considering the diagnosis of acute appendicitis in the differential diagnosis when examining any child with abdominal pain.

RESUMEN

PURPOSE: Treatment of ureteral calculi in the pediatric population represents a unique challenge. Extracorporeal shock wave lithotripsy (ESWL*) and ureteroscopy have been advocated for the treatment of such stones. We present our experience with ESWL monotherapy for ureteral stones in children in the last decade. MATERIALS AND METHODS: Between 1989 and 1999 we treated 21 boys and 17 girls with a mean age of 8 years (range 8 months to 14 years) with ureteral stones at our institution. Records were reviewed and analyzed for presentation, metabolic and anatomical anomalies, stone size and location, outcome and complications. Average stone size was 9.5 x 6.5 mm. (range 3 to 32). Stones were in the upper ureter in 17 cases, mid ureter in 2 and lower ureter in 19. All patients underwent ESWL with a Dornier HM3 lithotriptor under general anesthesia. Nephrostomies were placed in an anuric infant with bilateral ureteral obstruction and in 2 patients with nonfunctioning kidneys (4 renal units). Ureteral catheters were used in 15 patients for better identification and localization of the stone during ESWL. The catheters were removed immediately postoperatively. RESULTS: Of the patients 31 (81.5%) were free of stones after 1 session of ESWL, 5 (13.1%) after 2 and 1 after 3. One patient underwent ureteroscopy for residual fragments after 2 ESWL sessions. The stone-free rate following 1 ESWL session was 100% for ureteral calculi 10 mm. or smaller regardless of location. Of the 12 patients with stones larger than 10 mm. 8 (67%) were free of stones following 1 ESWL session. The overall success rate of ESWL was 97.3%. No child had postoperative urinary infection or ureteral obstruction. CONCLUSIONS: ESWL is an efficient and safe modality for the treatment of pediatric ureteral stones.

RESUMEN

Our armamentarium for the treatment of erectile dysfunction has recently been expanded by addition of Viagra and the MUSE. However, their long-term results are still unknown. The insertion of a penile prosthesis is invasive, expensive, and irreversible, but under optimal condition provides an acceptable, definitive solution for erectile dysfunction. We evaluated our long-term results with penile prosthesis insertion (PPI). From 1987-1998, 57 patients underwent PPI in our department. Mean age was 55 years and the common causes of erectile dysfunction were atherosclerotic disease (23), radical pelvic surgery (15), and diabetes mellitus (14). Semirigid prostheses were inserted in 12 and inflatable prostheses in 45, including 42 single-component and 3 multi-component prostheses. Recently we interviewed these patients by telephone, using a standard questionnaire. Those not satisfied with the surgical results (83% of the living patients) were examined in our clinic. Mean follow-up was 53 months. In 37 (84%) the prosthesis was mechanically functional (rates after 1, 5 and 10 years were 87.8%, 80%, and 75%, respectively). In only 2 (2.5%) had serious complications led to prosthesis removal. All mechanical failures had occurred in those with inflatable prostheses after a mean of 48.5 months (range 4-113). At the time of the survey 68% were sexually active and 64% were satisfied with the surgical result. We conclude that PPI is safe treatment for erectile dysfunction. Although the rate of mechanically functioning prostheses decreases with time, modern multi-component prostheses may lead to better mechanical results.

RESUMEN

PURPOSE: Urethral strictures are narrowing of the urethra caused by fibrosis due to excessive collagen production in response to an insult. We evaluated the effects of halofuginone, a potent inhibitor of collagen alpha1(I) gene expression, on experimentally induced urethral strictures in vivo and on rat urethral fibroblasts in vitro. MATERIALS AND METHODS: Applying coagulation current to the male rat urethra produced urethral strictures. Halofuginone was given to the animals for 7 days, starting on the day of stricture formation, either orally at 1 and 5 ppm in the diet or by injection of 0.03% halofuginone solution into the urethra. All rats were sacrificed on day 21. Collagen alpha1(I) gene expression was evaluated by in situ hybridization, collagen content by sirius red staining and urethral morphology by urethrogram. RESULTS: Coagulation current produced reproducible strictures with a typical urethrogram appearance, which were associated with increases in collagen alpha1(I) gene expression and collagen content at the stricture site. Halofuginone injected into the urethra or orally at 5 ppm normalized the urethrogram and prevented increases in collagen alpha1(I) gene expression and collagen content. Halofuginone at a concentration of 10-8 M. inhibited the collagen secreted by fibroblasts derived from the rat male urethra, which was due to inhibition of the collagen alpha1(I) gene expression. CONCLUSIONS: Halofuginone prevented stricture formation and may become an important mode of therapy in the prevention of restenosis during urethral stricture formation.

RESUMEN

An 8-year-old girl was born with crossed fused renal ectopia and neurogenic bladder due to sacral agenesis. Due to progressive upper tract deterioration and incontinence despite clean intermittent catheterization and pharmacotherapy with anticholinergic agents, the patient underwent augmentation colocystoplasty at the age of 4 years. Four years after surgery the girl was readmitted because of persistent febrile urinary tract infection, persistent metabolic acidosis, and intermittent watery diarrhea. A cystogram revealed a fistula between the dome of the augmented bladder and the transverse colon. The fistula was successfully resected. The presence of enterovesical fistula should always be suspected in a patient with augmented bladder who have late onset of urinary tract infection, metabolic acidosis, and diarrhea.

RESUMEN

STUDY OBJECTIVES: To determine whether isolated eardrum perforation is a marker for concealed blast lung injury in survivors of terrorist bombings. METHODS: Survivors who arrived at hospitals after 11 terrorist bombings in Israel between April 6, 1994, and March 4, 1996, were examined otoscopically by ear, nose, and throat specialists. All patients with eardrum perforation underwent chest radiography and were hospitalized for at least 24 hours for observation. The clinical course and final outcome of patients with isolated perforation of the eardrums and of those with other blast injuries were surveyed. RESULTS: A total of 647 survivors were examined; 193 (29.8%) of them sustained primary blast injuries, including 142 with isolated eardrum perforation and 51 with other forms of blast injuries (18 with isolated pulmonary blast injury, 31 with combined otic and pulmonary injuries, and 2 with intestinal blast injury). Blast lung injury was promptly diagnosed on admission by physical examination and chest radiography. No patient presenting with isolated eardrum perforation developed later signs of pulmonary or intestinal blast injury (mean 0%; 95% confidence interval, 0% to 2.7%). CONCLUSION: Isolated eardrum perforation in survivors of explosions does not appear to be a marker of concealed pulmonary blast injury nor of a poor prognosis. Therefore, in a mass casualty event, persons who have sustained isolated eardrum perforation from explosions may safely be discharged from the emergency department after chest radiography and a brief observation period.

RESUMEN

The optimal treatment of post-pneumonic thoracic empyema in children is controversial. In this retrospective study, we review our seven-year experience with open surgical drainage in this condition. Between July 1, 1989, and June 30, 1996, 20 children (median age 2.7 years, range 1-8 years) underwent thoracotomy for post-pneumonic empyema in our department. The diagnosis of thoracic empyema was established by the combination of exudate in a pleural tap and the demonstration of multi-loculated pleural effusion by either chest ultrasound or computerized tomography of the chest. The surgical approach was through a posterolateral mini-thoracotomy under general anesthesia. Intrapleural debris, gelatinous, and fibrinous material were evacuated and drains were placed, under vision, at the most dependent pleural locations. The mean length of pre-hospital illness was 5 days (S.D. 3.1 days) and the mean hospital length of stay in a pediatric ward prior to surgery, during which all children received intravenous antibiotics, was 9.4 days (S.D. 7.7 days). A causative pathogen was identified in 8 cases: Streptococcus pneumoniae in 6 cases, Streptococcus group A, and H. influenzae each in one case. Cultures from the pus removed during surgery were sterile for all 19 children who received antibiotics for more than 24 hours prior to surgery. Within 48 hours after surgery, fever dropped to < 37.5 degrees C in 85% of the cases. The postoperative course was uneventful in all cases and the children were discharged home 9 days (S.D. 2.8 days) after surgery. We conclude that open mini-thoracotomy and removal of the entire empyema sac is a safe and curative procedure for children with thoracic empyema.

RESUMEN

OBJECTIVE: To assess the long-term results of the Stamey vesicourethral suspension for stress urinary incontinence. METHODS: A total of 72 case records of women who underwent the Stamey procedure in the years 1985-1991 was reviewed. Every patient had a full preoperative evaluation including filling cystometry, urethral pressure profilometry and imaging of the kidneys and bladder. The long-term subjective results were determined by a telephone interview with the patients, utilizing a standard questionnaire. A successful result was defined as no need for pads under any circumstances. Every patient who reported on persistent or recurrent incontinence was requested to return for reevaluation in the urology clinic. RESULTS: The long-term success rate of the Stamey procedure in 63 evaluable patients was 69.8% (mean follow-up: 90 months). In 19 women, the operation had failed. About 80% of the failures were evident within 2 years after surgery. The long-term success rate of surgery in 28 women with pure stress incontinence was 93%. When mild irritative symptoms were present before surgery (29 patients) the subjective success rate was 65.5%, and in 6 patients with severe urge symptoms the success rate was only 33%. The difference between these groups was highly significant (p = 0.003). No correlation was found between the age of the patient at surgery, the number of children delivered by the patient, the grade of stress incontinence, the duration of symptoms before surgery or a history of a previous operation for stress incontinence and the success rate of the operation. CONCLUSIONS: The Stamey vesicourethral suspension is characterized by a relatively high and long-standing success rate. This procedure has an important place in the treatment of women with urinary stress incontinence.
