PURPOSE: Despite the advent of nerve sparing radical prostatectomy some men experience erectile dysfunction. Many of these men have vasculogenic erectile impairment in the form of arterial insufficiency or venous leakage. Recent data imply that early postoperative injection therapy may decrease the rate of erectile dysfunction. We defined hemodynamic patterns in patients who underwent bilateral nerve sparing radical prostatectomy to assess the chronology of venous leakage development and ...

OBJECTIVES: To evaluate the impact of normalization of testosterone levels in men with documented hypogonadism and erectile dysfunction on erectile function and sexual satisfaction. Although the data support the role of testosterone in the preservation of libido and nocturnal erectile function, the evidence supporting the use of testosterone supplementation in hypogonadal men with erectile dysfunction is weak.

METHODS: This analysis used two validated questionnaires, the International ...

OBJECTIVE: To define the type of orgasmic dysfunction in men after radical prostatectomy (RP), as absence of orgasm and orgasmic pain are recognized complaints, and changes in orgasm may lead to significant sexual dissatisfaction.

PATIENTS AND METHODS: Using an unvalidated questionnaire, demographic, erectile function and orgasmic function questions were answered by 239 patients who had previously undergone a retropubic RP.

RESULTS: Of the 239 patients, 22% had no change in orgasm ...

INTRODUCTION: . Failure to recover erectile function after radical prostatectomy (RP) may result from venous leak as a sequela of neuropraxia-induced erectile tissue damage. Venous leak portends a poor prognosis for erections recovery as well as phosphodiesterase type 5 inhibitor (PDE5i) response.

AIMS: To define the impact of RP nerve-sparing status on venous leak prevalence and chronology.

METHODS:

STUDY POPULATION: men who underwent RP for localized prostate cancer, had functional ...

The testis of patients with nonobstructive azoospermia (NOA) harbors sperm in approximately 30% to 60% of cases. Use of an operating microscope has been shown to result in better sperm retrieval rates. This investigation was undertaken to evaluate the ability of a modified microsurgical approach using magnifying loupes (3.5x) to improve the rates of sperm retrieval during testis sperm extraction (TESE). The study group consisted of patients with NOA who underwent TESE. Before December ...

INTRODUCTION: Sildenafil citrate is a highly effective erectogenic agent. However, predicting which patients will respond to this agent is often difficult. While the patient response to this agent is dependent on the nitric oxide-guanylate cyclase-cyclic guanosine monophosphate cascade, the integrity of penile arterial flow and venocclusive mechanism is also important. Duplex Doppler penile ultrasonography can reliably document penile hemodynamics. This study aimed at defining response ...

OBJECTIVE: To assess the efficacy of sildenafil in increasing penile glans tumescence and improving patient satisfaction in men with a penile prosthesis, as this remains a major treatment for erectile dysfunction but a common complaint is the lack of glans engorgement.

PATIENTS AND METHODS: To determine whether sildenafil combined with a penile prosthesis improves satisfaction, patients used an implant alone for at least 1 month, after which they completed the International Index of ...
