Immediate sexual rehabilitation by simultaneous placement of penile prosthesis in patients undergoing radical prostatectomy: initial results in 50 patients.

OBJECTIVES: To evaluate the results of simultaneous placement of a penile prosthesis with radical prostatectomy. METHODS: From June 1993 to June 1996, 50 men underwent a combination procedure of non-nerve sparing radical retropubic prostatectomy and placement of a penile prosthesis. We performed a retrospective chart review of these patients, examining patient age, preoperative prostate-specific antigen level, Gleason score, operative time, estimated blood loss, analgesic use, length of hospital stay, time until intercourse, and complications. This group was compared with a group of 72 men undergoing radical prostatectomy alone during the same time interval. RESULTS: No significant differences were noted in preoperative patient variables. The mean operative time for prosthesis insertion was 82 minutes, and the mean time to sexual intercourse was 12.7 weeks. No prosthesis infections have occurred, with a mean follow-up of 1.7 years. Four men (8%) have required revision of their inflatable penile prosthesis. There were no significant differences between the combination procedure and radical prostatectomy alone with regard to estimated blood loss, length of hospital stay, or analgesic use. CONCLUSIONS: Simultaneous placement of a penile prosthesis during radical prostatectomy provides early return to sexual function, with no apparent increase in morbidity. Further study will be required to determine the impact of combination surgery on psychosocial adjustment and quality of life.

Occult prostate cancer in men with low serum testosterone levels.

OBJECTIVE: To determine the prevalence of occult prostate cancer in men with low serum total testosterone or free testosterone levels. DESIGN: Retrospective analysis of a consecutive series of men. SETTING: Academic teaching hospital. PATIENTS: Seventy-seven men with low total testosterone or free testosterone levels, with normal results of digital rectal examination and prostate-specific antigen (PSA) levels of 4.0 ng/mL or less. The mean age was 58 years. INTERVENTIONS: Sextant prostate needle biopsies with ultrasound guidance. MAIN OUTCOME MEASURES: Results of prostate needle biopsies, transrectal ultrasound, prostate volume, PSA level, PSA density, total and free testosterone levels. RESULTS: Prostate cancer was identified in 14% (11/77) of the entire group and in 10 men (29%) aged 60 years or older. The median age for men with cancer was 64 years. Histologic examination showed Gleason scores of 6 or 7 for all cancers. No significant differences were noted between the cancer and benign groups with regard to PSA level, PSA density, prostate volume, total testosterone level, or free testosterone level. CONCLUSIONS: A high prevalence of biopsy-detectable prostate cancer was identified in men with low total or free testosterone levels despite normal PSA levels and results of digital rectal examination. These data suggest that (1) digital rectal examination and PSA levels are insensitive indicators of prostate cancer in men with low total or free testosterone levels, and (2) PSA levels may be altered by naturally occurring reductions in serum androgen levels.

Detached ciliary tufts in the epididymis: a lesson in applied anatomy.

We report a case of detached ciliary tufts (DCTs) discovered in the aspirate from an epididymal cyst in a 30-year-old man undergoing epididymal exploration for obstructive azoospermia. The specimen was initially misdiagnosed as a parasite due to its appearance and spontaneous motion on fresh smear. Since standard urology and histology texts identify ciliated cells only in the efferent duct of the male genital tract, the source of DCTs in this patient was mysterious. However, on further review, histologic studies have demonstrated that the first portion of the epididymis represents an extension of the efferent ducts and is lined with cilia. The fact that the caput epididymis is composed of branched efferent ducts has significant implications for our understanding of congenital absence of the vas, epididymal sperm aspiration, spermatoceles, and epididymal physiology.

Experience with the penile prosthesis and artificial urinary sphincter.

The therapy of two common urologic problems, erectile dysfunction and urinary stress incontinence, has been revolutionized over the last 20 years by the incorporation of principles of hydraulic mechanics into the field of silicone prosthesis implantation. The inflatable penile prosthesis is surgically implanted into men with impotence due to organic or psychogenic etiology. The artificial urinary sphincter has found widespread use in males and females in both the adult and pediatric populations with stress incontinence from a variety of causes. Associated with these popular devices are various complications relating to the anatomic site as well as the host's immunologic response. The use of these implants, as well as the technologic innovations resulting from various adverse effects, are reviewed herein.
