Intraoperative urethral pressure profilometry as an adjunct to bladder neck reconstruction

Area of Science:

• Urology
• Pediatric Surgery

Background:

• Bladder neck reconstruction and suspension are surgical procedures to treat urinary incontinence.
• Assessing the effectiveness of these procedures requires objective measurements of urethral function.

Purpose of the Study:

• To evaluate the utility of intraoperative urethral pressure profilometry in bladder neck reconstruction and suspension.
• To determine if bladder neck suspension improves urethral closure pressure and continence length.

Main Methods:

• Performed 17 bladder neck reconstructions with suspension between 1975 and 1984.
• Utilized intraoperative urethral pressure profilometry before and after bladder neck suspension.
• Assessed postoperative urinary continence via parental interviews.

Main Results:

• Achieved a continence length of 25–35 mm and urethral closure pressure >60 cm water in all patients.
• Bladder neck suspension increased continence length in all patients.
• Bladder neck suspension resulted in at least a 2-fold increase in urethral closure pressure.

Conclusions:

• Intraoperative urethral pressure profilometry is a valuable tool for confirming adequate bladder neck resistance post-surgery.
• Achieving an initial closure pressure of at least 60 cm water and ensuring anterior fixation are crucial for urinary continence.
• Bladder neck suspension effectively enhances urethral resistance and continence length.
