RESUMEN

OBJECTIVE: Several studies have tried to show a link between inflammation and cancer. In prostate cancer (PCa) development, this question is still not completely elucidated. The aim of the study was to investigate, whether the presence of inflammation in the first series of prostate biopsies was a factor of risk. PATIENTS AND METHODS: In this retrospective study, we examined prostate biopsy specimen of 220 consecutive patients, who had undergone repeat prostate biopsies in our department. The first screening round was performed between 2000 and 2005. These first prostate biopsies were examined by two pathologists blinded to the patient's follow-up. Inflammation and several histological criterions were evaluated: acute/chronic and focal/diffuse inflammation, atrophy, high grade PIN (HGPIN) and ASAP. We compared PCa incidences rates (IR) for the different histologic markers using chi(2) analysis and estimated the relative risk (RR) of PCa. RESULTS: Two hundred and one patients were included definitively with a median follow-up of 2.1 years (42 days - 8.9 years, period between the first and the last biopsy). One hundred and twenty-six patients (62.7%) were identified with inflammation in the first biopsies (inflammatory group [IG]). Ninety-seven patients (48.3%) had PCa, 58 from the IG. PCa IR did not differ significantly between patients with or without inflammation (RR: 0.9, p=0.6). CONCLUSIONS: According to these data, the presence and type of histological inflammation on initial prostate biopsies did not seem to be a risk factor for the development of PCa.

RESUMEN

The authors report the case of a bilateral rupture of the corpora cavernosa associated to a total disruption of the urethra resulting from blunt trauma during sexual intercourse. This association is a rare urologic case of emergency which most often take place during sexual intercourse (0.4% of the urologic cases of emergency). When both corpora cavernosa and urethra are fully disrupted, an internal penis amputation appears, compromising the vascularization and the erectional and micturitional prognosis. The rupture of the urethra is the first complication to search. Early diagnosis and surgical treatment allow a precise assessment of the lesions and a good functional result.

RESUMEN

The authors report a case of stage N3 pure testicular seminoma associated with paradoxical elevation of alphafoetoprotein (AFP). Despite the absence of histological arguments after review of the slides, this lesion was considered to be a stage pT1 N3 M0 S3 non seminomatous germ cell tumour with a poor prognosis. Simple surveillance was proposed following normalization of tumour markers, regression of retroperitoneal masses and negative PET scan. Laboratory and then clinical relapse at three months was treated by salvage chemotherapy followed by retroperitoneal lymph node dissection. The presence of embryonic carcinoma in one of the residual masses led to a revision of the initial histological diagnosis. The rare data of the literature indicate a variable approach according to alphafoetoprotein levels.

RESUMEN

OBJECTIVE: To standardize interpretation and comments of prostate-specific antigen (PSA) assay results by clinical pathology laboratories in office practice. MATERIAL: From September 2004 to May 2006, interpretation and comments of PSA assay results performed by 100 different laboratories were analysed retrospectively. RESULTS: Nineteen different PSA assay kits were used. The so-called "normal" value for total PSA was less than 4 ng/ml for two-thirds of kits. Determination of the free PSA/total PSA ratio (91 cases) was based on a cut-off value ranging from 10 to 25% and the frequent laboratory comments (89 cases) more often referred to benign prostatic hyperplasia (51 case) than prostate cancer (nine cases). CONCLUSION: The marked diversity of PSA assay techniques currently used and the divergent interpretations by various laboratories lead to problems of interpretation for both practitioners and patients.

RESUMEN

Cystic lymphangioma of the adrenal gland are rarely encountered tumoural formations with no clinical expression. Pre-operative diagnosis is difficult. Echography and CT scan are essential exploratory techniques, diagnosis is histological. Usually surgical exploration is indicated due to uncertain diagnosis. We report a new case of cystic lymphangioma of the adrenal gland and a review of recent literature.

RESUMEN

The authors report a case of renal cell carcinoma in a horseshoe kidney and discuss diagnostic and therapeutical aspects arising from this combination. Renal carcinoid tumors and nephroblastoma seems to be more frequent in this malformation. Diagnosis of horseshoe kidney may be difficult and angiography examination is very useful to confirm renal anomaly, tumor situation, and to plan the surgical approach because vascularization vary case to case. Heminephrectomy adapted to neoplasic localisation remains the essential treatment.

RESUMEN

We report the case of a 48 year-old woman presently with a pararenal tumor, with a history of pyelotomy in 1978 for the extraction of a renal pelvic stones. Results of surgery showed a foreign body. The clinical and diagnostic aspects of retained surgical gauze have been discussed and the need for radio-opaque markers in them have been emphasized.

RESUMEN

OBJECTIVE: Acucise balloon catheter has been proposed as an alternative to open surgery for the treatment of strictures of the ureteropelvic junction because of its low morbidity and the short hospital stay following the endoscopic procedure. The objective of this study was to evaluate the results of this technique applied to patients developing strictures after surgical reimplantation of the ureterovesical (UV) or uretero-intestinal (UI) junction. MATERIAL AND METHODS: Between March 1997 and January 2000, 12 strictures (11 patients) were treated by Acucise balloon catheter via an antegrade and/or retrograde approach with double J stenting for an average of 6 weeks (range: 4 to 12 weeks): 6 uretero-ileal strictures (3 Bricker, 1 uretero-ileoplasty, 1 enterocystoplasty and 1 Kock pouch) and 6 ureterovesical strictures (Lich-Grégoir or Faquin UV reimplantations after gynaecological, vascular or endoscopic surgery). The median postoperative follow-up was 16 months (range: 10 months-36 months). A good result was defined by the absence of recurrence of the stricture evaluated both clinically and radiologically (regression of stasis measured by IVU and/or ultrasonography). RESULTS: The mean operating time was 70 min and the mean hospital stay was 4.8 days (range: 3 and 14 days). Only one intraoperative complication was observed (migration of the double J stent to the kidney). The operation was successful in 8 patients (75%). The success rate was 83% for ureterovesical strictures and 50% for uretero-ileal strictures. A history of previous irradiation appeared to be a factor of failure. CONCLUSION: The Acucise procedure is a minimally invasive and effective (75% success rate) treatment option for the treatment of postoperative stricture after ureteric reimplantations. In our department, this option is considered to be first-line treatment, as surgical reimplantation is reserved for failures of the endoscopic technique.

RESUMEN

Spontaneous rupture of the bladder is a rare disease which raises real diagnostic and therapeutic problems. Based on three new cases of spontaneous rupture of the bladder in the absence of any trauma and a review of the literature, the authors discuss the various diagnostic, prognostic and therapeutic aspects of this unusual lesion, secondary to multiple aetiologies, predominantly inflammatory causes. Idiopathic rupture of the bladder is particularly serious compared to other forms of traumatic or iatrogenic rupture. Late diagnosis caused by the absence of pathognomonic signs and the generally insidious clinical course at least partly contribute to this severity. Neoplastic forms have a very poor prognosis.

RESUMEN

Emphysematous pyelonephritis (EPN) is a rare form of renal suppuration defined by the presence of pus and gas or bacterial origin within the renal parenchyma. It is associated with a high mortality in the absence of rapid and effective treatment. Emergency nephrectomy constitutes the reference treatment. Percutaneous drainage associated with medical treatment is an alternative in patients with localized or bilateral lesions or in the case of solitary kidney. The authors report 3 cases of EPN treated by percutaneous drainage combined with medical treatment for a localized lesion in two cases and nephrectomy in one case of disseminated multilocular lesion with an uneventful course in all three cases.

RESUMEN

The pheochromocytoma is a medullo-adrenal tumor which develops at the cost of the chromaffin cells. It appears in 11-19% of cases of von Hippel-Lindau's disease (VHL), is often bilateral, and the symptomatology is often crude: arterial hypertension is frequently isolated and unstable, and the classic triad of headache, palpitations and sweating is quite rarely observed. We report four observations of bilateral pheochromocytomas in patients with von Hippel-Lindau's disease (three with phenotype IIA and one with phenotype IIB). The tumor was bilateral during the diagnosis in three cases; in the fourth patient, the attack on the contralateral adrenal gland came two years after the first adrenalectomy. All the patients had undergone an adrenalectomy by open surgery after a short preparation of 48 hours; replacement therapy was begun in each patient. Morbidity was low, and the patients submitted to a prolonged follow-up in order to screen for the onset of future lesions of VHL.

RESUMEN

UNLABELLED: Obstruction of the lower ureter by pelvic cancer requires a palliative treatment. Percutaneous derivation is often performed as an emergency. If obstruction is limited to the peri-meatic area (a few mm or a cm) resection of the ureteral orifice can be enough to catheterize the obstructed ureter. Stenting of the ureter can be done even if the obstruction is longer, using the extra vesical repermeabilization. METHODS: A guide wire is passed via the nephrostomy, and ureteral stent is passed over the guide wire. Dye additionned with methylene blue is injected tovisualize the lower extremity of the ureter. A regular resectoscope is placed transuretraly, and resection is conducted using X ray localisation with a C arm and several incidences. The tissue resected first is usually extravesical, in the adipous perivesical tissue. Dissection of this area can be performed bluntly with the tip of the resectoscope until the ureter is reached. At this time, the resectoscope is used to open the lower extremity of the ureter, localized with the C arm. It is important to open widely the ureter, so as to be sure to catheterize easily this opening with a ureteral catheter. A double J can then be passed easily. Tunnel of several cm can be performed using this technique. RESULTS: Seven patients with pelvic cancer with obstruction of the last cm of the pelvic ureter were included in this series. They were recurrent prostate cancer already treated with hormone therapy, stage T3, T4. All procedures were performed under rachianesthesia or general anesthesia according to general status. After this procedure normal miction were obtain in all patients and nephrostomies were removed. This technique is possible for extended pelvic obstruction. Blunt dissection with the endoscope is usualy blood less. This palliative procedure can be done in patients with poor general condition and allows for a better quality of life than nephrostomy or urinary diversions.
