RESUMO

The ventral phalloplasty (VP) has been well described in modern day penile prosthesis surgery. The main objectives of this maneuver are to increase perceived length and patient satisfaction and to counteract the natural 1-2 cm average loss in length when performing implantation of an inflatable penile prosthesis. Similarly, this video represents a new adaptation for partial penectomy patients. One can only hope that the addition of the VP for partial penectomy patients with good erectile function will increase their quality of life. The patient in this video is a 56-year-old male who presented with a 4.0x3.5x1.0 cm, pathologic stage T2 squamous cell carcinoma of the glans penis. After partial penectomy with VP and inguinal lymph node dissection, pathological specimen revealed negative margins, 3/5 right superficial nodes and 1/5 left superficial nodes positive for malignancy. The patient has been recommended post-operative systemic chemotherapy (with external beam radiotherapy) based on the multiple node positivity and presence of extranodal extension. The patient's pre-operative penile length was 9.5 cm, and after partial penectomy with VP, penile length is 7 cm.

RESUMO

INTRODUCTION: The limitations of traditional ureteral stents in patients with deficiencies in ureteral drainage have resulted in frequent stent exchanges. The implementation of metallic stents was introduced to improve the patency rates of patients with chronic upper urinary tract obstruction, obviating the need for frequent stent exchanges. We report our clinical experiences with the use of metallic ureteral stents in the management of poor ureteral drainage. MATERIALS AND METHODS: Fifty patients underwent metallic ureteral stent placement from 2009 to 2012. Stent failure was defined as an unplanned stent exchange, need for nephrostomy tube placement, increasing hydronephrosis with stent in place, or an elevation in serum creatinine. Stent life was analyzed using the Kaplan-Meier methodology, as this was a time dependent continuous variable. A cost analysis was similarly conducted. RESULTS: A total of 97 metallic stents were placed among our cohort of patients: 63 in cases of malignant obstruction, 33 in the setting of cutaneous ureterostomies, and 1 in an ileal conduit urinary diversion. Overall, stent failure occurred in 8.2% of the stents placed. Median stent life was 288.4 days (95% CI: 277.4-321.2 days). The estimated annual cost for traditional polymer stents (exchanged every 90 days) was $9,648-$13,128, while the estimated cost for metallic stents was $4,211-$5,313. CONCLUSION: Our results indicate that metallic ureteral stent placement is a technically feasible procedure with minimal complications and is well tolerated among patients. Metallic stents can be left in situ for longer durations and provide a significant financial benefit when compared to traditional polymer stents.

RESUMO

UNLABELLED: The surgical management of patients with symptomatic metastatic or locally advanced recurrences involving the penis remains poorly characterized. The aim of the present abstract and video is to detail our experience in the surgical management of a specific patient with a locally advanced symptomatic recurrence of penile sarcoma secondary to prostate cancer treated with primary brachytherapy. MATERIALS AND METHODS: A 70 year old male patient initially treated for localized prostate cancer with interstitial brachytherapy at an outside facility developed an unfortunate secondary malignancy consisting of a locally advanced penile sarcoma involving as well the prostate and base of the bladder. Despite our best efforts to control his pain, he developed a very symptomatic local recurrence with a secondary penile abscess and purulent periurethral drainage. At this time, it was felt a surgical resection consisting of a total penectomy, urethrectomy, cystoprostatectomy, and ileal conduit urinary diversion would be the best option for local cancer control in this particular patient. RESULTS: The patient underwent the surgical resection without any complications as illustrated in this surgical video, with a jejunal intestinal mass identified at the time of surgery which was resected with a primary bowel anastomosis performed. The patient was discharged from hospital uneventfully with his symptomatic local recurrence being successfully managed and the patient no longer requiring oral narcotics for pain control. The pathological report confirmed a locally advanced sarcoma involving the penile, prostate, and bladder which was resected with negative surgical margins and the jejunal mass was confirmed to represent a small bowel sarcoma metastatic site. CONCLUSION: As highlighted in the present video, the treatment of a symptomatic sarcoma local recurrence contiguously involving the penis can be successfully managed provided the patient is informed of the potential morbidity and psychosocial implications imparted by performing a total penectomy and adjacent organ resection.

RESUMO

INTRODUCTION AND OBJECTIVE: Ureteral duplication is the most common urologic abnormality. The upper pole ureter can sometimes be associated with a ureterocele. In rare cases the ureteral insertion is extravesical and can result in significant hydroureteronephrosis. Patients can present with urinary tract infection, abdominal mass or urinary obstruction. Traditional procedures include ureteral reimplantation, ureteroureterostomy or heminephroureterectomy. These reconstructive procedures are technically challenging in small infants, especially when the hydroureteronephrosis is severe. In some cases a distal cutaneous ureterostomy is performed for immediate drainage followed by definitive surgery when the child is older. We describe our initial experience with a novel cystoscopic technique which provides drainage of the upper pole ureter and avoids the need for an incision or stoma. MATERIALS AND METHODS: A 3 month-old boy presented with urinary tract infections and failure to thrive. Ultrasound revealed severe upper pole hydroureteronephrosis. Voiding cystourethrography did not reveal vesicoureteral reflux or the presence of a ureterocele. The patient underwent cytoscopy. The ectopic ureteral orifice was not identified. A transurethral, transvesical needle puncture and confirmatory ureteropyelography was used to access the dilated upper pole ureter. Guidewire passage, followed catheter dilation then allowed creation of a new ureteral orifice using a holmium laser. RESULTS: The patient tolerated the procedure well. He was discharged after overnight observation. The hydronephrosis improved, urinary tract infections have not recurred and the patient rapidly improved feeding and weight gain. CONCLUSION: Trans-Urethral Neo-Orifice creation is a minimally invasive option for initial decompression for patients with obstructive ureteral ectopia.

RESUMO

PURPOSE: To present the surgical technique of ventral phalloplasty as an adjunct procedure to the classic prosthetic surgery. MATERIALS AND METHODS: In this video we demonstrate how to perform a ventral phalloplasty in a patient that has undergone a penile prosthesis implantation. Our technique consists of: delineation of the penile scrotal web, excision of this redundant skin, and re-approximation of the wound to mimic the natural median raphe. RESULTS: The ventral phalloplasty improves the perception of phallic length, as well as patients' satisfaction after prosthetic surgery. CONCLUSION: Penile length perception is the main concern of patients that have undergone penile prosthesis implantation. In this video we demonstrate that the ventral phalloplasty can improve perception of phallic length, and can be an important adjunct to the classic prosthetic surgery.

RESUMO

INTRODUCTION: The management of a post-chemotherapy retroperitoneal mass secondary to testicular cancer can present a surgical challenge when involving adjacent organs or major vascular structures. We present the first video of a retroperitoneal lymph node dissection (RPLND) with IVC (inferior vena cava) thrombectomy, caval wall resection resulting from metastatic non-seminomatous germ cell testis (NSGCT) cancer. METHODS: In this surgical video, we highlight important surgical considerations in the management of a postchemotherapy retroperitoneal mass with direct IVC wall invasion and level 2 thrombus in such a patient. RESULTS: A 34 year old man underwent a right inguinal orchiectomy for a mixed NSGCT (embryonal, yolk sac, and teratoma components) and elevated serum tumor markers. He underwent systemic chemotherapy (BEP regimen x 4 cycles) with subsequent near normalization of tumor markers. His post-chemotherapy imaging revealed a 6 cm residual retroperitoneal mass with a level 2 IVC tumor thrombus and suspected direct infrarenal IVC wall invasion from the mass. The patient underwent an open post-chemotherapy RPLND, IVC thrombectomy, IVC resection and grafting. The final pathology report of the retroperitoneal mass revealed teratoma with no viable germ cell tumor elements and negative surgical margins. His intra-operative and post-operative stages were unremarkable with his IVC graft remaining patent and no evidence of disease recurrence at last follow-up. CONCLUSION: We present the first surgical video of a post-chemotherapy RPLND with IVC thrombectomy, caval wall resection and grafting for metastatic NSGCT. The final pathology report of teratoma with no viable tumor highlights the local vascular invasive potential of such pathology.

RESUMO

PURPOSE: Various treatment options are available for small incidentally detected kidney masses, including surveillance, partial nephrectomy and probe ablative therapies. When partial nephrectomy is considered, the procedure can be safely approached laparoscopically, either pure or robot assisted, in experienced hands. Laparo-endoscopic single site (LESS) surgery is a novel approach for partial nephrectomies in well selected cases. In this video, we present our experience with the LESS retroperitoneal partial nephrectomy using the Gelpoint device. MATERIAL AND METHODS: A 63 year old male patient with a BMI of 31, and a history of a T1c prostate cancer, had a 1.5 cm right posterior lower pole renal enhancing mass discovered incidentally on a three phase CT scan. With the patient under general anesthesia, and in a full flank position, a LESS retroperitoneal partial nephrectomy was performed using a 3 cm transverse incision below the tip of the 12th rib. The following instruments and devices were used: A gelpoint device for single incision port of entry, one 10 mm and two 5 mm trocars used through the gelpoint, one 5 mm Olympus HD endoeye flexible tip camera, one roticulator scissors, and one articulating graspers. RESULTS: Operative time, EBL, and hospital stay were 1 hour, 5 ml, and 23 hours, respectively. The pathology result confirmed a benign hemorrhagic cystic mass. The visual analog scale (0-10) for pain at recovery, 6 hours post op, and 23 hours post op was 5, 3, and 1 point, respectively. The patient tolerated clear liquids and regular diet at 6 and 16 hours, after the procedure. At one month of follow-up, the patient is asymptomatic and practically scarless. CONCLUSIONS: LESS retroperitoneal partial nephrectomy is safe and feasible in selected cases such as small exophytic posterior renal masses. The retroperitoneal approach avoids mobilization of the colon and kidney to access the posterior surface. Instrument clashing, limited range of motion, and CO2 leakage, can be some difficulties encountered during single port retroperitoneal surgery. However, the Gelpoint device gives a great seal in the flank position and allows the relocation of trocars, without loss of CO2 pressure, to prevent instrument clashing during different parts of the procedure.
