Can prostate biopsies affect erectile function?

The impact of transrectal ultrasound (TRUS)-guided prostate biopsies on erectile function was prospectively studied. Forty-six men (median age: 67.51 years) who underwent TRUS-guided prostate biopsies completed the International Index of Erectile Function (IIEF)-5 questionnaire at the day of the biopsy, 1 and 3 months later. Erectile dysfunction (ED) severity was classified into five categories. Concomitant ED-related systemic diseases and/or medications that could affect erectile function were also recorded. The paired t-test was used for statistical analysis. The median IIEF-5 score was 15.91 prior to biopsies, while 1 and 3 months after, the median IIEF-5 score was 14.33 and 14.81 respectively (P > 0.05). Prior to prostate biopsies, ED was reported by 38 patients (82.60%): mild ED in 39.13%, mild to moderate in 19.56%, moderate in 15.21% and severe ED in 8.69%. Concomitant ED-related systemic diseases and/or medications were recorded in 28 patients (60.86%). One month after, ED was revealed in 42 patients (91.30%): mild ED in 26.08%, mild to moderate in 30.43%, moderate in 19.56%, and severe ED in 15.21%. Three months post-biopsy, ED was reported by 41 patients (89.13): mild ED in 21.73%, mild to moderate in 28.26%, moderate in 21.73%, and severe ED in 17.39%. Overall, three and two patients (6.52% and 4.34%) had prostate biopsy attributed ED (i.e. without concomitant ED-related disease or medication) 1 and 3 months after prostate biopsies. TRUS-guided prostate biopsies did not induce ED in a statistically significant manner. Evaluating potency at referral for TRUS-guided prostate biopsies is advisable.

Urinary diversion in high-risk elderly patients: modified cutaneous ureterostomy or ileal conduit?

OBJECTIVES: To evaluate the efficacy and safety of the type of urinary diversion during radical cystectomy in high-risk elderly patients by comparing a modified cutaneous ureterostomy with the ileal conduit urinary diversion. METHODS: Of 481 patients who underwent radical cystectomy between 1993 and 2002, 54 individuals older than 75 years with an American Society of Anesthesiologists score of 3e, 4, or 4e were characterized as high risk. These patients were grouped according to those who underwent a modified cutaneous ureterostomy (group 1, 29 patients) and those who underwent ileal conduit urinary diversion (group 2, 25 patients). Student's t and Fisher's exact tests were used for statistical analysis. RESULTS: The patients in group 2 had a longer operative time (P < 0.001), an increased need for blood transfusion (P = 0.025), an increased need for intensive care monitoring (P = 0.032), and a longer mean hospitalization time (P < 0.001) than the patients in group 1. In group 2, we recorded statistically greater rates of intraoperative complications (P = 0.035), early medical and surgical complications (P = 0.031 and P = 0.012, respectively), and late surgical complications (P = 0.004). The intraoperative, early, and late surgical complication rate was 13.7%, 24.1%, and 17.2% in group 1 and 40%, 60%, and 56% in group 2, respectively. One patient in group 2 died in the early postoperative period. CONCLUSIONS: Cutaneous ureterostomy represents a simplified alternative for urinary diversion in high-risk elderly patients. It can be performed quickly, with few early and late postoperative complications compared with the ileal conduit operation.

Colonoscopy effects on serum prostate specific antigen levels.

INTRODUCTION: To evaluate the colonoscopy effects on serum levels of prostate specific antigen (PSA) and PSA ratio. SUBJECTS AND METHODS: Thirty men were studied (median age 68 years, range 32-89). All of them had their serum PSA (total and free) measured 24 hours prior to colonoscopy and also 24 hours, 7 and 30 days after procedure. RESULTS: 14 of 30 (47%) patients, had significantly (p = 0.045) increased Total PSA levels 24 hours after the procedure, 14 (47%) patients had insignificantly (p = 0.139) increased levels 7 days after, while 13 (43%) of them had insignificantly (p = 0.061) increased levels 30 days after colonoscopy. In 7 patients (23%), with total PSA levels in the "gray zone" (4-10 ng/ml) before colonoscopy, a near significant (p = 0.063) raise in PSA ratio was also observed 24 hours after. CONCLUSION: Flexible colonoscopy affect serum PSA (free and total) levels in certain patients. Special attention must be given to those patients with PSA levels in the "gray zone" before colonoscopy.

Percutaneous nephrolithotomy to remove a cartridge detonating cap mimicking a renal pelvic stone 12 years after renal trauma.

Complications of gunshot injuries of the kidney usually present in the early postoperative period. We describe a case of a cartridge's plastic detonating cap retained in the renal pelvis of a young male patient for 12 years. Renal colic was the cause of admission. This missile's part was mimicking a renal stone on both an intravenous urogram and a CT scan. The nature of the "stone" was identified during a percutaneous nephrolithotomy procedure during which the foreign body was removed.
