Effects of cryoablation on short-term development of urinary fistulas in the porcine kidney.

Purpose: To determine the effect of cryoablation on the collecting system in the porcine kidney and the possible development of pelvic injury or fistula.

Materials And Methods: Six kidneys from three domestic swine were utilized. Under MRI guidance, a 3-mm cryoprobe was placed percutaneously and advanced to a point adjacent to the collecting system.

Three-year follow-up of laser prostatectomy versus transurethral resection of the prostate in men with benign prostatic hyperplasia.

Objectives: To present our 3-year data comparing laser prostatectomy and transurethral resection of the prostate (TURP) for benign prostatic hyperplasia (BPH). Laser prostatectomy was one of the first new minimally invasive treatment modalities for BPH, and few reports of the long-term results of this treatment regimen have been published.

Methods: One hundred men with BPH in whom medical therapy had failed were randomized to undergo either laser prostatectomy or TURP.

Prospective study of cancer detection in black and white men with normal digital rectal examination but prostate specific antigen equal or greater than 4.0 ng/mL.

Background: The serum prostate specific antigen (PSA) concentration with no clinical evidence of prostate carcinoma is higher and more variable in black than in white American men. The influence of this phenomenon on relations between race, PSA, and cancer detection in men with a PSA greater than or equal to 4.0 ng/mL has not been investigated.
