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.

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.

OBJECTIVETo evaluate the sleeve circumcision and preputioplasty with modified incision for the treatment of patients with phimosis or redundant prepuce.

METHODSFive hundred and seventy-six patients with phimosis or redundant prepuce underwent operations of sleeve circumcision or preputioplasty with modified incision. The conventional incision was modified and changed into two opposite tortuous incisions.

RESULTSThe operation with modified incision had the following advantages: less blood loss, slight postoperative edema, no secondary bleeding or infection, quick recovery and good appearance of the penis.

CONCLUSIONThe sleeve circumcision and preputioplasty with modified incision is an excellent therapeutic option for phimosis and redundant prepuce.

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.

OBJECTIVETo investigate the effects of surgery treatment on serious penile lesions and malformation.

METHODSSixty-two patients, aged from 19 to 63 years old (mean 35 ys), were included in the study. Among them, 4 patients suffered from penis partial defection were respectively treated with restoring defective penis, penis lengthening and urethroplasty; three patients with penis completely missing were treated with penis reconstruction surgery; 22 cases with serious penile curvature were treated with the 16-dot plication technique (Lue's procedure); 15 cases with penile fracture were treated with conservative treatment for 1 case and with patch penis, corpus spongiosum, and deep penile dorsal vein ligation for 14 cases; 5 cases with post-operative complications of 3-pieces of penile prosthesis, including the prosthesis perforating to the urethra, water pump failure, broken connection tube, erection angle < 60 degrees and failure to expansion the corpus cavernosum, were treated by taking out prostheses, urethral repair cracks, replacement of the prostheses, excision of fibrosis scar and re-implantation prostheses respectively. Four cases with penis complete amputation were treated with the penis replantation; three cases of avulsion injury were treated with the replantation and free flap skin; 6 with Paget's disease of penises were treated with the lesion free skin buried in the scrotum and penis.

RESULTSAll these patients were followed up for 3 months to 4 years, with the average of 9 months. Among the 4 cases of penis partial defection, 2 patients were satisfied with the penile appearance and sexual function; 1 got some satisfactory and 1 was unsatisfied. Three cases with the loss of the penis completely were satisfied with both the postoperative appearance and urination, and 1 was not satisfied. Twenty-two cases of penile curvature deformities were corrected, and one case was recurrence. Fourteen of the 15 patients with penile fracture were followed, and all got the restoration of sexual function. Among them, 5 cases with post-operative complications, including mild bending, algopareunia, subcutaneous induration, poor hardness and poor sexual pleasure, were not further treated, and another case lost; Five cases with post-operative complications of three-pieces penile prosthesis were treated successfully, and 4 of their spouses were satisfied with their sexual function after operation, only 1 of their spouse not satisfied. Among four cases with complete amputation of penis, two cases of penis were replanted successfully while two necrosis. Three cases with avulsion were treated with skin grafting successfully. All 6 cases with penile Paget's disease were followed for 2 -4 years, and free skin grafts were all survival. One patient died of brain metastases 18 months after operation and five cases were disease-free survival.

CONCLUSIONThe patients should be treated based on the procedure of andrological and urological surgery, together with microsurgical, flap or skin graft technique. The urologist should design personalized surgical procedure. Most of the patient's penis shape and erectile dysfunction can be reconstructed by our procedures, but some patients can not achieve the desired appearance or function of penis. New approaches of the treatment ought to be developed to restore both of the shape and function for those severe injury of the penis.

Objectives: to investigate the effectiveness and reliability of the combination of optical cystolithotripsy (OC) and transurethral prostatectomy (TURP) for the treatment of bladder calculi and obstructive benign prostates enlargement (BPE). Patients and methods: from September 1999 to December 2003, 63 patients who had bladder stones and BPE were treated with combined OC and TURP; 45 patients who had bladder stones with no infravesical obstruction were treated with OC alone. In the same period, the records of random selection of 561 patients with BPE were treated by TURP. The operative duration time, the length of hospital stay, the duration of urethral catheterization, outcome and complication of the procedures for each patient were reviewed. Results: The mean duration of surgery were significantly longer with combined OC and TURP than with OC or TURP alone (p<0.05), but not of hospital stay and urethral catheterization. Stones free rates were 100% after OC alone and combined OC and TURP. The postoperative average mean peak flow rates were 13.2 ml/s in the combined OC and TURP group and were 13.7 in the TURP alone group. The complication rates were 13.6% for the TURP procedure, 5% for the OC alone and 21% for the combined OC and TURP (p<0.05). Conclusion: Simultaneous treatment with OC and TURP did not change the effectiveness of these procedures, but caused additional morbidity.
Prostatectomy ; Transurethral Resection of Prostate

With the recent increase in the elderly population, and the Westernization of the diet and increased consumption of meat products, a significant rise in the incidence of prostate cancer has been noted in the Republic of Korea. In cases with localized prostate cancer and sufficiently long life expectancy, the standard treatment is surgical resection of the prostate. Such surgical treatment is so far the only modality demonstrated through randomized prospective studies to be beneficial in terms of disease-specific survival; this procedure involves not only surgical removal of the prostate but also pelvic lymphadenectomy for accurate staging and neurovascular bundle preservation to aid in postoperative functional recovery. Prostatectomy can be carried out either with an open technique, laparoscopically, or under robot assistance. Reviews of the literature and meta-analyses have shown that laparoscopic and robot-assisted procedures offer significant reductions in blood loss and transfusion rates and advantages in terms of recovery from postoperative complications such as incontinence and impotence over open prostatectomy. However, no long-term oncologic outcomes are available for laparoscopic or robot-assisted procedures, and the long-term prevalence of incontinence and impotence for these two methods doesnot differ significantly from those for open prostatectomy, despite the laparoscopic and robot-assisted procedures being far more costly. Therefore, surgical treatment of prostate cancer should be carefully decided on following ample deliberation of various factors including the stage, age, comorbidities, and economic status of the patient and provision of sufficient information to the patient.

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.

Peyronie's disease is a common condition resulting in penile deformity, psychological bother, and sexual dysfunction. Erectile dysfunction is one common comorbid condition seen in men with Peyronie's disease, and its presence significantly impacts treatment considerations. In a man with Peyronie's disease and significant erectile dysfunction who desires the most reliable treatment, penile prosthesis placement should be strongly considered. In some instances, such as those patients with relatively mild curvature, prosthesis placement alone may result in adequate straightening. However, many patients will require additional straightening maneuvers such as manual modeling, penile plication, and tunica albuginea incision with or without grafting. For patients with severe penile shortening, penile length restoration techniques may also be considered. Herein, we provide a comprehensive clinical review of penile prosthesis placement in men with Peyronie's disease. Specifically, we discuss preoperative indications, intraoperative considerations, adjunctive straightening maneuvers, and postoperative outcomes.
