Study Shows Penile Length Shorter After Prostate Cancer Surgery

The focus of most research on the side effects of prostate cancer surgery has been erectile dysfunction and urinary incontinence.

A new research conducted by researchers in Brazil focused on the length of penises after prostate cancer surgery or radical prostatectomy.

The overall findings of the research indicate that the penile length of most men that underwent the procedure was shortened by 1 cm but the full length was later restored after 48 months.

Researchers from the Pedro Ernesto Memorial Hospital in Rio de Janeiro, Brazil carried out the research. The study was lead by Eloisio Alexsandro da Silva, MD. Details of the research have also been published in the “Urology”.

An article posted in the Renal & Urology News by Jody A. Charnow and dated December 10, 2012, provided insights on how the study was carried out. In the online post, it is revealed that 105 men were evaluated after they have undergone radical prostatectomy (RP). Stretched-penis measurements were obtained preoperatively and at 3, 6, 12, 24, 36, 48, and 60 months after RP.

The researchers used the International Index of Erectile Function-Erectile Function questionnaire to evaluate erectile function. To measure penile length, the investigators used the stretched length of the flaccid penis, from the pubopenile skin angle to the end of the glans after the prepubic fat was depressed under maximum manual traction.

The mean stretched penile length three months post-operatively decreased significantly by an average of 1 cm from baseline, the researchers reported in Urology (2012;80:1293-1297).

This difference persisted until 24 months. At 36 months, the length differed  by 0.6 cm. At 48 and 60 months, the mean differences in penile length before and after surgery were not significant.

Conclusively, radical prostatectomy is a type of surgery carried out to remove the prostate gland after diagnoses has shown that cancer is confined within the prostate. The procedure is an effective means of treating prostate cancer but it comes with side effects like erectile dysfunctions and urinary incontinence.
