Bladder and sexual function after surgery for rectal cancer.

A C Kinn, U Ohman

    Diseases of the Colon and Rectum
    |January 1, 1986
    PubMed
    Summary

    Post-rectal surgery, bladder voiding issues and reduced sexual potency were observed in some men. However, objective bladder function remained largely unaffected, suggesting autonomic denervation primarily impacted sympathetic nerves.

    Area of Science:

    • Urology
    • Colorectal Surgery
    • Neuro-urology

    Background:

    • Rectal carcinoma surgery can impact adjacent autonomic nerves controlling bladder and sexual function.
    • Understanding these functional outcomes is crucial for patient management and surgical technique refinement.

    Purpose of the Study:

    • To evaluate the effects of rectal carcinoma surgery on bladder function and sexual potency.
    • To identify potential correlations between surgical approach and functional deficits.

    Main Methods:

    • Prospective study assessing bladder voiding and sexual function before and after surgery.
    • Objective urodynamic measurements (bladder capacity, residual volume, flow rate, detrusor pressure) were performed.
    • Patient-reported outcomes on voiding and sexual function were collected.

    Main Results:

    • Seven of 22 men experienced impaired urinary voiding post-surgery, with four requiring prostatic surgery.
    • Two years later, 8 of 16 men reported disturbed voiding, but objective bladder parameters showed no significant change.
    • Sexual potency was reduced in 5 of 10 men, including cases of retrograde ejaculation and erectile dysfunction.
    • Symptoms suggested sympathetic rather than parasympathetic denervation, potentially due to surgical plane dissection.

    Conclusions:

    • Postoperative bladder dysfunction after rectal surgery is less common objectively than subjectively reported.
    • Autonomic denervation, particularly sympathetic, may contribute to functional deficits.
    • Prostatic resection is recommended for men with prostatic symptoms alongside rectal cancer surgery.
