Postoperative Reduction in Postvoid Residual Urine Volume May Be Associated With Bladder Capacity Decrease Rather...

Area of Science:

• Urology
• Gynecology
• Pelvic Floor Disorders

Background:

• Pelvic organ prolapse (POP) frequently causes lower urinary tract symptoms (LUTS), particularly voiding difficulties.
• Surgical interventions like laparoscopic sacrocolpopexy (LSC) and transvaginal mesh (TVM) surgery can improve voiding function in POP patients.

Purpose of the Study:

• To evaluate longitudinal changes in bladder parameters after POP surgical repair.
• To assess postoperative voiding function and quality of life in POP patients.

Main Methods:

• Retrospective analysis of 216 POP patients undergoing LSC (n=86) or TVM (n=130).
• Preoperative and postoperative measurements included bladder capacity (BC), voided urine volume (VV), and post-void residual urine volume (PVR).
• International Prostate Symptom Score (IPSS), quality of life (QOL) score, and 60-min pad test were used to assess LUTS and QOL.

Main Results:

• BC significantly decreased post-LSC and post-TVM at various time points.
• PVR, IPSS, and QOL scores significantly decreased 3-12 months postoperatively in both groups.
• No significant differences in complication rates or 1-year outcomes (PVR, pad test, IPSS+QOL) between LSC and TVM.

Conclusions:

• Postoperative reduction in PVR after POP surgery may be associated with decreased bladder capacity at strong desire to void.
• This suggests a complex interplay between bladder capacity and voiding efficiency post-POP repair.
