To determine the safety and efficacy of the single-knot running versus interrupted technique for urethrovesical anastomosis during endoscopic extraperitoneal radical prostatectomy. ⋯ Both techniques provide satisfactory and similar functional results. However, because of its simplicity and shorter operative time, the single-knot running technique appears preferable.

To determine whether nadir prostate-specific antigen (PSA) levels within 12 months (nadir PSA12) after completion of radiotherapy (RT) can be used as an early marker of recurrence risk. ⋯ The results of this large, multi-institutional study have demonstrated that nadir PSA12 is predictive of clinical outcomes for patients with localized prostate cancer after RT. A high pretreatment PSA level and high nadir PSA12 will identify patients at particularly high risk who might benefit from early adjuvant therapy.

Midurethral polypropylene slings are popular procedures for the treatment of stress urinary incontinence in women. Several commercially manufactured sling kits are available that use proprietary monofilament polypropylene mesh placed between the vaginal wall and midurethral segment. The BioArc sling system is a hybrid sling system that uses polypropylene mesh for fixation and autologous fascia for suburethral support. We report what we believe to be the first case of vaginal erosion after midurethral sling placement using this hybrid system.

The detection of postoperative complications is a necessary quality-of-care endeavor. Despite its historical role, the Morbidity and Mortality (M&M) Conference depends on voluntary reporting and may be an insufficient mechanism for comprehensive complication surveillance. In response to this concern, we compared the concordance between complications voluntarily reported at the M&M Conference and those identified prospectively by the National Surgical Quality Improvement Program (NSQIP). ⋯ Compared with the NSQIP, the M&M Conference has a low (but variable) sensitivity for the detection of postoperative complications. Therefore, despite its limitations, the NSQIP may provide a better foundation for urologic quality improvement endeavors.

Comparative Study
Greater body mass index is associated with better pathologic features and improved outcome among patients treated surgically for clear cell renal cell carcinoma.
Obesity increases the risk of developing renal cell carcinoma (RCC); however, it remains unclear whether obesity is associated with RCC aggressiveness and survival. We used data from a large cohort of patients treated surgically for clear cell RCC to evaluate the association of obesity with the pathologic features of tumor aggressiveness and cancer-specific outcomes. ⋯ BMI offers little additional prognostic information beyond the accepted prognostic features; however, the association of an increased BMI with a less-aggressive disease profile at presentation warrants further exploration.
