    ABSTRACT: Early surgical management is the standard of care for penile fracture. Conservative treatment is an option with recent reports revealing lower success rates. We reviewed the data and long-term outcomes of patients with penile injury submitted to surgical or conservative treatment. Between January 2004 and February 2012, 42 patients with penile blunt trauma on an erect penis were admitted to our center. We analyzed the following variables: age, etiology, symptoms and signs, diagnostic tests, treatment used, complications and erectile function during the follow-up. One patient was excluded due to missing information. Thirty-five patients underwent surgical repair and 6 patients were submitted to conservative management. Mean follow-up was 19.2 months (range, 7 days to 72 months). The mean elapsed time from trauma to surgery was 21.3±12.5 hours. Trauma during sexual relationship was the main cause (80.9%) of penile fracture. Urethral injury was present in five patients submitted to surgery. Dorsal vein injury occurred in three patients with false penile fracture and concomitant spongious corpus lesion was present in three patients. During follow-up, 31 cases (88.6%) of the surgical group and four cases (66.7%) of the conservative group reported sufficient erections for intercourse, with no voiding dysfunction and no penile curvature. However, the remaining two patients (33.3%) from the conservative group developed erectile dysfunction and three patients (50%) developed penile deviation. Surgical approach provides excellent functional outcomes and lower complications. Early surgical management of penile fracture provides superior results and conservative approach should be avoided.

    ABSTRACT: Objective parameters in computed tomography (CT) scans that could predict calyceal access during percutaneous nephrolithotomy have not been evaluated. These parameters could improve access planning for percutaneous nephrolithotomy. We aimed to determine which parameters extracted from a preoperative multiplanar reconstructed CT could predict renal calyceal access during a percutaneous nephrolithotomy. From January 2009 through April 2011, 230 patients underwent 284 percutaneous nephrolithotomies at our institution. Sixteen patients presented with complete staghorn calculi, and 11 patients (13 renal units) were analyzed. Five parameters were extracted from a preoperative reconstructed CT and compared with the surgical results of percutaneous nephrolithotomy. Fifty-eight calyces were studied, with an average of 4.4 calyces per procedure. A rigid nephroscope was used to access a particular calyx, and a univariate analysis showed that the entrance calyx had a smaller length (2.7 vs. 3.98 cm, p = 0.018). The particular calyx to be accessed should have a smaller length (2.22 vs. 3.19 cm, p = 0.012), larger angles (117.6 vs. 67.96, p<0.001) and larger infundibula (0.86 vs. 0.61 cm, p = 0.002). In the multivariate analysis, the only independent predictive factor for accessing a particular calyx was the angle between the entrance calyx and the calyx to be reached (OR 1.15, 95% confidence interval [CI], 1.053-1.256, p = 0.002). The angle between calyces obtained by multiplanar CT reconstruction is the only predictor of calyx access.

    ABSTRACT: To determine whether the presence of median lobe (ML) affects perioperative outcomes, positive surgical margin (PSM) rates, and recovery of urinary continence after robot-assisted radical prostatectomy (RARP). We analyzed 1693 consecutive patients undergoing RARP performed by a single surgeon. Patients were analyzed in two groups based on the presence or not of a ML identified during RARP. Perioperative outcomes, PSM rates, and recovery of urinary continence were compared between the groups. Continence was assessed using validated questionnaires, and it was defined as the use of "no pads" postoperatively. A ML was identified in 323 (19%) patients. Both groups had similar estimated blood loss, length of hospital stay, pathologic stage, complication rates, anastomotic leakage rates, overall PSM rates, and PSM rate at the bladder neck. The median overall operative time was slightly greater in patients with ML (80 vs 75 min, P<0.001); however, there was no difference in the operative time when stratifying this result by prostate weight. Continence rates were also similar between patients with and without ML at 1 week (27.8% vs 27%, P=0.870), 4 weeks (42.3% vs 48%, P=0.136), 12 weeks (82.5% vs 86.8%, P=0.107), and 24 weeks (91.5% vs 94.1%, P=0.183) after catheter removal. Finally, the median time to recovery of continence was similar between the groups (median: 5 wks, 95% confidence interval [CI]: 4.41-5.59 vs median: 5 wks, CI 4.66-5.34; log rank test, P=0.113). The presence of a ML does not affect outcomes of RARP performed by an experienced surgeon.

    ABSTRACT: Laparoscopy has certainly brought considerable benefits to patients, but laparoscopic surgery requires a set of skills different from open surgery, and learning in the operating room may increase surgical time, and even may be harmful to patients. Several training programs have been developed to decrease these potential prejudices. to describe the laparoscopic training program for urological residents of the "Hospital das Clinicas" of the Sao Paulo Medical School, to report urological procedures that are feasible in dry and wet labs, and to perform a critical analysis of the cost-benefit relation of advanced laparoscopic skills laboratory. The laparoscopic skill lab has two virtual simulators, three manual simulators, and four laparoscopic sets for study with a porcine model. The urology residents during their first year attend classes in the virtual and manual simulator and helps the senior urological resident in activities carried out with the laparoscopic sets. During the second year, the urological resident has six periods per week, each period lasting four hours, to perform laparoscopic procedures with a porcine model. In a training program of ten weeks, one urological resident performs an average of 120 urological procedures. The most common procedures are total nephrectomy (30%), bladder suture (30%), partial nephrectomy (10%), pyeloplasty (10%), ureteral replacement or transuretero anastomosis (10%), and others like adrenalectomy, prostatectomy, and retroperitoneoscopy. These procedures are much quicker and caused less morbidity. Laparoscopic skills laboratory is a good method for achieving technical ability.

    ABSTRACT: Surgical treatment of lower extremity fractures commonly involves the use of orthopedic table with perineal post for countertraction. However, prolonged application of the perineal post has been associated with significant complications. We describe our experience in the management of genitoperineal cutaneous injuries associated with the use of a traction table. Six patients with genitoperineal complications attributed to the use of a traction table were treated at our institution over a period of 2 years. The patient's median age was 25 (range, 20-28) years and all had fractures caused by motor vehicle collision. We evaluated the clinical presentation of these perineal injuries, operative time, therapeutic approach, clinical outcomes, and hospitalization time. The mean operative time of the orthopedic surgery was 318 minutes +/- 128 minutes (range, 185-540). All patients developed a partial-thickness necrotic area involving the perineum and scrotum in 2 days to 15 days (mean, 7 +/- 5.4) after the surgery. Three patients developed infection of the necrotic tissue. All patients underwent surgical debridement 16.5 days +/- 6.5 days (range, 13-29) after the orthopedic surgery and only one debridement procedure was necessary in all cases. A primary wound closure was possible in one case, and in the other cases the wound healed completely by second intention. The mean hospitalization time was 26.3 days +/- 9.7 days (range, 19-44). Genitoperineal skin necrosis induced by perineal traction posttable is a morbid complication that demands surgical debridement and prolonged hospitalization for your treatment. There are many procedures available to reduce the risk of this complication that should be used more liberally by the orthopedic surgeons.
