PURPOSE: This study was conducted to perform a comparative analysis of the efficacy and safety of conventional transurethral resection of the prostate (TUR-P), transurethral resection in saline (TURIS), and TURIS-plasma vaporization (TURIS-V) when performed by a single surgeon for benign prostatic hyperplasia (BPH). MATERIALS AND METHODS: The clinical data of 73 consecutive men who underwent conventional TUR-P (39), TURIS (19), or TURIS-V (15) for BPH were retrospectively analyzed. All procedures were carried out by a single surgeon between October 2007 and April 2010. The patients were assessed preoperatively and perioperatively and were followed at 1, 3, and 6 months postoperatively. Patient baseline characteristics, perioperative data, and postoperative outcomes were compared, and major complications were recorded. RESULTS: In all groups, significant improvements in subjective and objective voiding parameters were achieved and were sustained throughout follow-up. TURIS-V had the shortest operation time compared with conventional TUR-P and TURIS (p=0.211). TURIS-V significantly decreased procedural irrigation fluid volume, postoperative irrigation duration, catheter duration, and hospital stay compared with conventional TUR-P and TURIS. There were no significant differences between the groups in hemoglobin levels or serum sodium levels before and after the operations. There were three transfusions and four clot retentions in the TUR-P group, and one transfusion and one clot retention in the TURIS group. The TURIS-V group had no complications. CONCLUSIONS: TURIS and TURIS-V were effective for the surgical treatment of BPH in addition to conventional TUR-P. TURIS-V was not inferior to conventional TUR-P or TURIS in terms of safety.

PURPOSE: The da Vinci(R) robot system has been used to perform complex reconstructive procedures in a minimally invasive fashion. Robot-assisted laparoscopic radical prostatectomy has recently established as one of the standard cares. Based on experience with the robotic prostatectomy, its use is naturally expanding into other urologic surgeries. We examine our practical pattern and application of da Vinci(R) robot system in urologic field. PATIENTS AND METHODS: Robotic urologic surgery has been performed during a period from July 2005 to August 2008 in a total of 708 cases. Surgery was performed by 7 operators. In our series, radical prostatectomy was performed in 623 cases, partial nephrectomy in 43 cases, radical cystectomy in 11 cases, nephroureterectomy in 18 cases and other surgeries in 15 cases. RESULTS: In the first year, robotic urologic surgery was performed in 43 cases. However, in the second year, it was performed in 164 cases, and it was performed in 407 cases in the third year. In the first year, only prostatectomy was performed. In the second year, partial nephrectomy (2 cases), nephroureterectomy (3 cases) and cystectomy (1 case) were performed. In the third year, other urologic surgeries than prostatectomy were performed in 64 cases. The first robotic surgery was performed with long operative time. For instance, the operative time of prostatectomy, partial nephrectomy, cystectomy and nephroureterectomy was 418, 222, 340 and 320 minutes, respectively. Overall, the mean operative time of prostatectomy, partial nephrectomy, cystectomy and nephrourectectomy was 179, 173, 309, and 206 minutes, respectively. CONCLUSION: Based on our experience at a single-institution, robot system can be used both safely and efficiently in many areas of urologic surgeries including prostatectomy. Once this system is familiar to surgeons, it will be used in a wide range of urologic surgery.

BACKGROUNDA virtual reality simulator provides a novel training model for improving surgical skills in a variety of fields. They can simulate a variety of surgical scenarios to improve the overall skills required for endoscopic operations, and also record the operative process of trainees in real-time and allow for objective evaluation. At present, some simulators for transurethral resection of the prostate (TURP) are available. The utility of virtual reality simulators in training of transurethral prostatectomy was investigated.

METHODSThirty-eight urologists were randomly selected to take part in a simulation based training of TURP using the TURPSim(TM) system. Pre and post-training global rate scale (GRS) scores and objective parameters recorded by the simulator were assessed. Then, questionnaires were filled out.

RESULTSCompared with baseline levels, the GRS scores of trainees increased (18.0 ± 4.0 vs. 12.4 ± 4.2, P < 0.001), while the rate of capsule resection (26.3% ± 0.6% vs. 21.2% ± 0.4%, P < 0.001), amount of blood loss ((125.8 ± 86.3) ml vs. (83.7 ± 41.6) ml, P < 0.001), external sphincter injury (3.6 ± 2.9 vs. 2.0 ± 2.0, P < 0.001) decreased significantly after training. Most trainees were satisfied with the simulator based training and believed that the simulator accurately mimicked actual surgical procedures and could help improve their surgical skills.

CONCLUSIONSAs a new method of training on transurethral prostatectomy skills, training of TURP using a virtual simulator can help urologists improve their surgical skills and safety. Therefore, the application of the TURPSim(TM) system in education and training of urologic surgery is warranted.

PURPOSE: The aim of this study was to analyze the outcomes of immediate primary repair (IPR) compared with delayed repair (DR) after initial suprapubic cystostomy. MATERIALS AND METHODS: We reviewed the records of 60 patients with bulbous urethral disruption after blunt trauma from February 2001 to March 2011. Seventeen patients who presented in an acute injury state underwent IPR; 43 patients underwent DR after the initial suprapubic cystostomy. None of the patients had undergone previous urethral manipulation. We compared the outcomes, including stricture, impotence, and incontinence, between the two management approaches. We also measured the time to spontaneous voiding, the duration of suprapubic diversion, and the number of days spent in the hospital. RESULTS: The median follow-up was 20.5 months (range, 13 to 59 months; mean, 23.3 months). Among 17 patients in the IPR group, strictures developed in 2 patients (11.7%), and among 53 patients in the DR group, strictures developed in 8 patients (18.6%, p=0.709). The incidences of impotence and incontinence were similar in both groups (17.6% and 0% in the IPR group vs. 27.9% and 4.6% in the DR group, p=0.520 and 1.000, respectively). The time to spontaneous voiding and the duration of suprapubic diversion were significantly shorter in the IPR group (average 27.3 and 33.4 days, respectively) than in the DR group (average 191.6 and 198.1 days, respectively; p<0.001 and <0.001). CONCLUSIONS: IPR may provide comparable outcomes to DR and allow for shorter times to spontaneous voiding and reduce the duration of suprapubic diversion.

Male acquired urinary incontinence can be a complication of radical prostatectomy and posterior urethroplasty. Mild urinary incontinence can be improved by pelvic floor exercises, biofeedback and medicine treatment. Severe urinary incontinence requires more active treatment, such as injection therapy, artificial urethral sphincter insertion, and bulbourethral sling. Recent progress in the treatment of male acquired urinary incontinence is reviewed in this article.

To describe the novel technique of ventral inlay substitution urethroplasty for the management of male anterior urethral stricture disease. A 58-year-old gentleman with multifocal bulbar stricture disease measuring 7 cm in length was treated using a ventral inlay substitution urethroplasty. A dorsal urethrotomy was created, and the ventral urethral plated was incised. The edges of the urethral plate were mobilized without violation of the ventral corpus spongiosum. A buccal mucosa graft was harvested and affixed as a ventral inlay to augment the caliber of the urethra. The dorsal urethrotomy was closed over a foley catheter. No intraoperative or postoperative complications occurred. Postoperative imaging demonstrated a widely patent urethra. After three years of follow-up, the patient continues to do well with no voiding complaints and low postvoid residuals. Ventral inlay substitution urethroplasty appears to be a safe and feasible technique for the management of bulbar urethral strictures.

OBJECTIVETo study 3 different strategies of urine drainage following hypospadias urethroplasty, the clinical nursing in their application, and their effects.

METHODSWe retrospectively analyzed the clinical data of 595 cases of hypospadias treated by urethroplasty. After surgery, 133 of the patients underwent urine drainage by suprapubic cystostomy (group A), 202 by urethral stent- tube indwelling (group B), and 260 by early initiative micturition with the urethral stent-tube (group C). All the patients received routine postoperative nursing care required for hypospadias repair.

RESULTSOperations were successfully completed in all the cases. Group C showed a remarkably shorter hospital stay and lower incidence rates of urinary fistula and urethral stricture than groups A and B (P<0.05), but there were no significant differences in the three indexes between A and B (P<0.05).

CONCLUSIONFor urine drainage following hypospadias repair, early initiative micturition with the urethral stent-tube can significantly reduce postoperative complications, decrease difficulties and workload of nursing care, and shorten the hospital stay of the patient.
