Short communicationPost-TURP obliterative urethral stricture: Unusual treatment and favourable result

Urethral stricture is a well-known complication after TURP. Most cases present with recurrence of lower urinary tract symptoms. In rare incidences, complete obliteration of the urethra is diagnosed. Management of such cases is challenging and usually associated with a poor outcome. We report a case of post-TURP obliterative urethral stricture that was managed successfully by Holmium laser core-through urethrotomy. On discharge, the patient was continent and voided well.Keywords: Urethral stricture; TURP; Holmium laserAfrican Journal of Urology (2013) 19, 18–2

Primitive Neuroectodermal Tumor (PNET) of the kidney: a case report

BACKGROUND: A case of Primitive Neuroectodermal Tumor (PNET) of the kidney in a 27-year-old woman is presented. Few cases are reported in the literature with a variable, nonspecific presentation and an aggressive behaviour. In our case, a radical nephrectomy with lymphadenectomy was performed and there was no residual or recurrent tumour at 24-month follow-up. METHODS: The surgical specimens were formalin-fixed and paraffin embedded. The sections were stained with routinary H&E. Immunohistochemistry was performed. RESULTS: The immunohistochemical evaluation revealed a diffuse CD99 positivity in the cytoplasm of the neoplastic cells. Pankeratin, cytokeratin AE1/AE3, vimentin, desmin, S100, cromogranin were negative. The clinical presentation and the macroscopic aspect, together with the histological pattern, the cytological characteristic and the cellular immunophenotype addressed the diagnosis towards primary PNET of kidney. CONCLUSIONS: Since sometimes it is difficult to discriminate between PNET and Ewing's tumour, we reviewed the difficulties in differential diagnosis. These tumors have a common precursor but the stage of differentiation in which it is blocked is probably different. This could also explain their different biological behaviour and prognosis

Case report Post TURP obliterative urethral stricture: Unusual presentation and favourable result

Introduction: Urethral stricture is a well known complication after TURP. Most of the cases present with recurrence of lower urinary tract symptoms. Infrequently, cases of complete obliteration of urethra is diagnosed. Management of these rare cases is always challenging and associated with poor outcome. We report a case of post TURP obliterative urethral stricture that was managed successfully by holmium laser core through urethroplasty. On discharge patient was continent and voided well. Conclusion: Holmium laser core through is a useful technique for management of these complicated cases with satisfying result. It should be done by experienced endourologist.Keywords: Urethral stricture; TURP; Holmium laserAfrican Journal of Urology (2013) 19, 78–8

Perioperative outcome of initial 190 cases of robot-assisted laparoscopic radical prostatectomy - A single-center experience

Objective: To analyze the perioperative outcome of the first 190 cases of robot-assisted laparoscopic radical prostatectomy performed at our center from July 2006 to December 2010. Materials and Methods: Operative and recovery data for men with localized prostate cancer undergoing robot-assisted radical prostatectomy at our center were reviewed. All surgeries were performed using the 4-arm da Vinci-S surgical robot. Preoperative data included age, body mass index (BMI), prostate specific antigen (PSA) level, prostate weight, biopsy Gleason score and TNM staging, while operative and recovery data included total operative time, estimated blood loss, complications, hospital stay and catheter time. These parameters were evaluated for the safety and efficacy of this procedure in our center. Results: The mean age of our patients was 65 ± 1.2 years. The mean BMI was 25.20 ± 2.88 and the median PSA was 14.8 ng/ml. Majority of our patients belonged to clinical stage T2 (51.58%). The mean total operative time was 166.44 ± 11.5 min. Six patients required conversion to open procedure and there was one rectal injury. The median estimated blood loss was 302 ± 14.45 ml and the median duration of hospital stay was 4 days. The overall margin positivity rate was 12.63%. Conclusion: Despite our limited robotic surgery experience, our perioperative outcome and complication rate is comparable to most contemporary series. Robot-assisted laparoscopic prostatectomy (RALP) is easy to learn and provides the patient with the benefits of minimally invasive surgery with minimal perioperative morbidity
