To determine whether improved prostate sampling by the extended biopsy scheme also improves the accuracy of the biopsy Gleason score (bGS). Because most prostate cancer cases are now detected at an early stage with a low prostate-specific antigen level, the bGS may be the most important factor in therapeutic decision-making. Sextant biopsy schemes had poor correlation with prostatectomy Gleason scores. Extended prostate biopsies have replaced the sextant scheme because of the former's greater cancer detection rate. ⋯ The use of an extended prostate biopsy scheme significantly improves the correlation between the bGS and prostatectomy Gleason score and reduces the risk of upgrading to a worse Gleason group at prostatectomy.

To examine the relationship between the percentage of positive biopsies (PPBs) and freedom from biochemical recurrence (FFBR) in men treated with low-dose-rate prostate brachytherapy (LDRPB) alone. The PPBs has been associated with FFBR in men treated with radical prostatectomy and external beam radiotherapy for prostate cancer. ⋯ The PPBs is an important independent predictor of FFBR after LDRPB alone. The FFBR after LDRPB in the group of patients with more than 50% PPBs was poor.

Patent urachus accounts for 10% to 15% of all reported urachal abnormalities in the literature. Treatment in the past has relied on immediate surgery. Conservative therapy with bladder catheter drainage, resulting in spontaneous closure, has not been described. ⋯ One week of urethral catheterization resulted in spontaneous closure of the patent urachus. This case suggests that initial treatment should consist of urethral catheterization for 1 to 2 weeks, followed by repeat voiding cystourethrogram. If the patent urachus still persists, one should proceed to surgical correction.

To evaluate the relationship between pretreatment postvoid residual urine (PVR) less than 100 mL and brachytherapy-related urinary morbidity. ⋯ The selection of patients with a pretreatment PVR of less than 100 mL was associated with rapid IPSS resolution, the absence of prolonged (more than 3 days) catheter dependency, and the elimination of postbrachytherapy surgical intervention for bladder outlet obstruction.

Randomized Controlled Trial
Novel device to assist urethrovesical anastomosis during laparoscopic radical prostatectomy.
We evaluated a novel urethral sound (Benique sound-Karl Storz) to assist suturing during laparoscopic radical prostatectomy. This sound provides for a more secure grip compared with the traditional sound, thereby affording controlled traction of the gland during the procedure and smooth coordinated movements of the sound during the anastomosis.
