Objective: Preliminary study to assess the feasibility and safety of percutaneous nephrolithotomy (PCNL) as an ambulatory procedure. Patients and Methods: Between February 2011 and September 2012, 84 patients with renal calculi fulfilling the inclusion criteria were admitted to the Urology Department of Benha University Hospitals for PCNL. All patients were subjected to a full medical history, clinical, laboratory and radiological examinations. Tubeless PCNLs were done in the supine position, and an antegrade double-J stent was inserted. Operative time and intraoperative complications were recorded. Postoperatively, the hematocrit value, postoperative pain and analgesics, need of blood transfusion, stone-free rate, and length of hospital stay were recorded. Stable patients that could be safely discharged within 24 hours after surgery were considered ambulatory. Results: All cases of tubeless PCNL were successfully done and no cases converted to open surgery. The overall stone-free rate was 91.7%, the mean postoperative pain score measured by the visual analog scale was 4.4 ± 1.2, the mean overall hematocrit deficit was 4.8 ± 2.2% and the mean hospital stay was 33.4 ± 17.5 hours. Ambulatory PCNL was accomplished in 60 out of 84 patients (71.4%) and double-J stents were removed 7-10 days postoperatively. In the non-ambulatory cases, double-J stents were removed after auxillary procedures were done according to each case. Conclusion: PCNL can be safely done on an ambulatory basis under strict criteria, but further studies are needed to confirm and expand these findings.

ObjectiveTo compare the outcome of treatment planning using multislice computed tomography (CT) or intravenous urography (IVU) for supine percutaneous nephrolithotomy (PCNL).Patients and methodsThe study included 60 patients with renal stones, all treated by supine PCNL, between March 2011 and October 2012. The patients were divided randomly into two equal groups; in group 1 30 patients had the PCNL access planned based on IVU findings, and in group 2 the PCNL access was planned based on multislice CT images. All patients were suitable for PCNL, based on a plain abdominal film and ultrasonography, and with a body mass index of <30 kg/m2. The exclusion criteria were renal anomalies and bleeding diathesis. All data from both groups for the mean time taken to gain percutaneous access, operative duration, fluoroscopic time, access difficulty, stone-free rate and intraoperative morbidity were collected and analysed statistically.ResultsThe mean (SD) time taken to gain percutaneous access was longer in group 1 than group 2, at 22.2 (1.76) vs. 13.1 (1.62) min (P < 0.001), as were the operative duration, at 81.9 (14.9) vs. 58.8 (7.6) min (P < 0.001), and fluoroscopic time, at 3.5 (1.7) vs. 2.2 (1.3) min (P = 0.002). In group 1 there were four cases (13%) in which there were difficulties in establishing percutaneous access, while in group 2 there were none (P = 0.003). There was intraoperative morbidity in three patients (10%) in group 1 and two (7%) in group 2.ConclusionMultislice CT is a safer, more accurate and noninvasive imaging technique than IVU for mapping the pelvicalyceal system. It saves time and is essential in choosing the optimal percutaneous access into the pelvicalyceal system for a safe and successful PCNL.

Purpose To assess the outcome of transurethral plasmakinetic vaporization (PKVP) in the management of benign prostatic hyperplasia (BPH).Patients and methods From August 2010 to May 2012, 60 patients with obstructive LUTS due to BPH were included in the study. All patients were evaluated by International Prostate Symptom Score (IPSS), general examination, digital rectal examination, PSA, routine laboratory examinations, pelvi-abdominal ultrasound, trans-rectal ultrasound, and uroflowmetry. Patients with Qmax of <10 mL/sec., an IPSS of >8 and a prostate volume of >40 mL underwent transurethral PKVP.Results Mean age of the patients was 66.8±4.5 years. The mean times of the operation, post-operative bladder irrigation, and post-operative catheterization were 63.8±13.9 minutes, 15.2±5.7 hours, and 23.9±5.2 hours, respectively. At 3 months of follow-up, there were significant reductions in the mean IPSS from 23.4±3.5 to 9.2±3.7 (P=0.4), mean PSA from 3.03±2.2 ng/mL to 1.2±1.04 ng/mL (P value=0.02), mean post voiding residual urine from 149.8±59.5 mL to 46.9±24.1 mL (P value <0.01), and mean prostate volume from 72.8±10.3 mL to 22.7±6.1 mL (P value <0.01). Also, there was a statistically significant increase in the mean Q max. from 8.7±2.4 mL/s to 19.5±3.5 mL/s (P value <0.01).Conclusion PKVP is an effective and safe treatment option in the management of symptomatic BPH.

Objectives: The objective of this article is to evaluate the importance of a second-look transurethral resection of bladder tumour (TURBT) in patients with newly diagnosed superficial bladder cancer and its impact on subsequent treatment plan. Methods: We carried out a prospective study on 100 consecutive patients with newly diagnosed superficial bladder cancer in whom a second-look TURBT was performed two to six weeks after initial resection. We assessed the incidence of residual tumours, sufficiency of initial pathological staging and grading. We also assessed the need for re-staging and grading after the second-look TURBT. Results: Forty-five out of 75 patients (60%) who underwent second-look TURBT had no tumours, 18 (24%) had visible residual tumours and 12 (16%) had microscopic residual tumours. Of the 30 (40%) patients with residual tumours, five had pTa, three had carcinoma in situ (CIS), 12 had pT1, and 10 had pT2 disease. Upstaging and change of treatment plan as a result of the second-look TURBT were necessary in 18/75 (24%) cases, of which 10 cases (13%) underwent radical cystectomy for muscle-invasive tumours. Conclusions: A second cystoscopy with or without TURBT is recommended two to six weeks after initial resection of stage Ta and T1 bladder tumours in patients with high-grade transitional carcinoma of the bladder or in patients with multiple tumours. Second-look cystoscopy in this category of patients may reveal the need for early change of treatment plan in about 25% of patients.

Introduction: To assess the feasibility of single-incision laparoscopic surgery (SILS) in some urological surgeries. Material and Methods: This prospective study was conducted on 40 patients (27 males and 13 females) from January 2010 to June 2011. Six procedures were done, SILS renal cyst decortication (n = 10), SILS varicocelectomy (n = 10), SILS orchiopexy (n = 10), SILS nephrectomy (n = 3), SILS pyelolithtomy (n = 6) and SILS adrenalectomy (n = 1). Results: Postoperative complications included ileus (10%) and fever (10%) in SILS renal cyst ablation. SILS varicocelectomy had postoperative sequalae as persistent varicocele (10%) and hydrocele (10%). SILS orchiopexy was also done with a success rate 100% in this series. SILS pyelolithotomy was successfully done in 5 out of 6 patients and only 1 patient was converted to conventional laparoscopy. In SILS nephrectomy 1 patient out of 3 was converted to conventional laparoscopy. Conclusion: SILS in urology has proven to be safe and feasible in the hands of experienced laparoscopic surgeons, using specially designed ports and instruments in selected patients.
