Can malleable penile prosthesis implantation improve voiding dysfunction in men with concurrent erectile dysfunction...

A buried penis causes voiding dysfunction and limits penetrative sexual intercourse. This pilot study evaluates the urinary outcomes in men with buried penis following insertion of malleable penile implants.

Men with buried penis and co-existing urinary problems and erectile dysfunction underwent malleable penile prosthesis implantation were reviewed in a prospective ethics approved database. Patient demographics, flow rate (Qmax), International Prostate Symptom Score (IPSS), Patient Global Impression of Improvement (PGI-I) score, International Index of Erectile Function (IIEF)-5 score, Sexual Encounter Profile (SEP) and overall satisfaction score (on a 5-point scale) were recorded.

A total of 12 men (age 55 to 72 years) were reviewed, and the average gain in penile length post-implant, as measured from the pubis to the tip of the glans penis, was 6.8 (3 to 8) cm. There was a significant improvement in IIEF-5 score (8.2 vs. 22.5; p=0.029) post-implant, and more than half of patients were able to resume normal sexual intercourse and positive SEP-2 and SEP-4 were reported in 9 (75%) and 8 (67%) patients. There were no significant intraoperative or postoperative complication. Significant improvement in Qmax (8.4 ml/s vs. 18.6 ml/s; p=0.042) and IPSS (24.5±5.5 vs 15.5±3.5; p=0.038) were observed. More than two-thirds (83%) reported PGI-I score at 1 or 2, while 9 (75%) patients scored a 5/5 in overall satisfaction rate.

Malleable penile implants increases penile length and improves urinary function in a highly select group of men with a buried penis and erectile dysfunction.
