We assessed the construct validity of a commercially available, virtual reality transurethral prostate resection simulator.

Materials

and Methods: Participants performed 2, 5-minute transurethral prostate resection exercises on a standardized virtual reality prostate. Data from the first exercise were discarded. Simulator based metrics from the second exercise were tabulated, including tissue resected in gm, number of cuts, coagulation time, number of coagulation attempts, tissue per cut in gm and blood loss. Complications were recorded. selleckchem Performance metrics were compared between groups based on urological training level and prior real-world experience with transurethral prostate resection.

Results: A total of 35 participants with varied levels of transurethral prostate resection experience completed the exercise. Several performance metrics had statistically significant correlations with urology training level and prior experience with transurethral prostate resection. There was a positive correlation of all measures of experience with mass resected, mass resected per cut and blood loss. Number of cuts correlated significantly

with transurethral prostate resection experience in the previous year. Complications were present in most groups with medical students more likely to encounter external urethral sphincter and rectal injuries.

Conclusions:

We report the construct validity of a commercially available, virtual reality transurethral prostate Dinaciclib resection simulator. The more experienced participants resected more BAY 1895344 solubility dmso tissue in a more efficient manner but with increased blood loss. Further investigations are needed before the widespread application of transurethral prostate resection simulators for training, certification and accreditation.”
“Purpose: We evaluated the long-term results and durability of photoselective vaporization and holmium laser ablation as surgical treatment of small to medium prostates in a prospective, randomized study in men with obstructive benign prostatic hyperplasia.

Materials and Methods: From March 2005 to April 2007 we randomly allocated 109 patients with a prostate gland of less than 60 cc to prostate photoselective vaporization (52) or holmium laser ablation (57) and evaluated them 1, 2 and 3 years postoperatively. Functional followup included measurement of maximum urinary flow rate, post-void residual urine, International Prostate Symptom Score, quality of life, International Index of Erectile Function and prostate specific antigen.

Results: Mean +/- SD preoperative prostate volume was 33.1 +/- 14.5 and 37.3 +/- 13.6 in the laser ablation and vaporization groups, respectively. All functional parameters improved significantly compared to baseline values in each group.
