OBJECTIVE To evaluate the effect of the early use of the vacuum erection device (VED) on erectile dysfunction (ED) and penile shortening after radical retropubic prostatectomy (RP), as these are important concerns for men choosing among treatment alternatives for localized prostate cancer. PATIENTS AND METHODS Twenty‐eight men undergoing RP were randomized to early intervention (1 month after RP, group 1) or a control group (6 months after RP, group 2) using a traditional VED protocol. An International Index of Erectile Function (IIEF) score of >11 (no, mild or mild to moderate ED) was required as a baseline criterion for inclusion in the study. Only patients in whom unilateral or bilateral nerves were spared were subsequently randomized. Patients in group 1 followed a daily rehabilitation protocol consisting of 10 min/day using the VED with no constriction ring, for 5 months. Patients were evaluated with the IIEF‐5 questionnaire and measurements of penile flaccid length, stretched length, prepubic fat pad, and midshaft circumference before and at 1, 3, 6, 9 and 12 months after RP; the mean (range) last follow‐up visit was 9.5 (6–12) months after RP. RESULTS The mean (sd) baseline IIEF scores were similar in groups 1 and 2, at 21.1 (4.6) and 22.3 (3.3), respectively (P = 0.54). The IIEF scores were significantly higher in group 1 than group 2 at 3 months, at 11.5 (9.4) vs 1.8 (1.4) (P = 0.008) and at 6 months, at 12.4 (8.7) vs 3.0 (1.9) (P = 0.012) after RP. There were no significant changes in penile flaccid length, prepubic fat pad, or mid‐shaft circumference in either group. Stretched penile length was significantly decreased at both 3 and 6 months, by ≈ 2 cm (P = 0.013) in group 2. By contrast, stretched penile length was preserved in group 1 at all sample times. At the last follow‐up, the proportion of men with a mean loss of penile length of ≥ 2 cm was significantly lower in group 1 than group 2 (two/17, 12%, vs five/11, P = 0.044). CONCLUSIONS Initiating the use of a VED protocol at 1 month after RP improves early sexual function and helps to preserve penile length.

Alfuzosin improves the patient discomfort associated with stone passage and decreases the time to distal ureteral stone passage but it does not increase the rate of spontaneous stone passage.

Our study confirms that Uriprene stents are biocompatible and provide good renal drainage. They hold promise for decreasing the need for a secondary procedure and stent related morbidity, such as infection and irritative symptoms.

Heparin coating does not decrease bacterial adherence to ureteral stents. Drug eluting antimicrobials have an inhibitory effect on bacterial adherence and the Polaris stent showed the least bacterial adherence of the nondrug eluting ureteral stents tested.

Instrumentation is the key to success in endourology. Indeed, endourology could be redefined as "enginurology," as the marriage between engineering and urology, and developing instrumentation to improve patient outcomes is the key facilitator in the advancement of minimally-invasive techniques. This review article will identify the evidence base that supports our current recommendations for equipment used during ureteroscopy.
