Urodynamic study on postsurgical bladder function in cervical cancer treated with systematic nerve-sparing radical...

Area of Science:

• Urogynecology
• Surgical Oncology
• Oncologic Surgery

Background:

• Cervical cancer treatment often involves radical hysterectomy, potentially impacting bladder function due to autonomic nerve damage.
• Nerve-sparing surgical techniques aim to mitigate these side effects, improving patient quality of life.

Purpose of the Study:

• To evaluate postsurgical bladder function using urodynamic studies in cervical cancer patients who underwent nerve-sparing radical hysterectomy.
• To compare bladder function outcomes between patients with and without successful autonomic nerve preservation.

Main Methods:

• Urodynamic studies were conducted on 27 cervical cancer patients before and 12 months after nerve-sparing radical hysterectomy.
• Patients were divided into two groups: Group A (n=22) with successful nerve preservation on at least one side, and Group B (n=5) with unsuccessful nerve preservation.

Main Results:

• Group A showed no significant changes in bladder compliance, maximum flow rate, or residual urine volume post-surgery.
• Group B experienced significantly increased abdominal pressure at maximum flow and decreased detrusor contraction pressure compared to Group A.
• Bladder sensation was diminished in 60% of Group B patients, whereas all Group A patients retained bladder sensation.

Conclusions:

• The described nerve-sparing radical hysterectomy technique appears effective in preserving postsurgical bladder function.
• Successful autonomic nerve preservation is crucial for maintaining normal bladder function and sensation after cervical cancer surgery.
• Further prospective randomized trials are warranted to confirm efficacy regarding quality of life and survival.
