Key Surgical Points
- Place the patient in the lithotomy position with legs fully abducted. Indwell a urinary catheter to preliminarily assess the position and length of the urethra.
- Inject hydrodissection fluid and incise the anterior vaginal wall mucosa. Use the index finger as a guide during puncture to avoid perforating the lateral vaginal sulcus mucosa.
- Slide the trocar toward the patient’s shoulder or below the junction of the pubic symphysis and inferior pubic ramus. Immediately adjust the trocar to the posterior side of the pubic symphysis once a slight breakthrough sensation is felt after gentle force application. Press the puncture handle firmly to allow the trocar to penetrate closely behind the pubic bone. The suprapubic abdominal puncture site is 2 cm lateral to the midline, right against the superior pubic margin.
- Monitor urine color throughout the puncture procedure to confirm no injury to the bladder or urethra.
- Instill 250–300 mL normal saline into the bladder. Adjust sling tension by compressing the bladder area. A slight urine leakage resembling "tear drops" at the urethral meatus after compression indicates appropriate tension. Flatten the sling, then suture the anterior vaginal wall mucosa.
- Indwell an indwelling urinary catheter for 24 hours postoperatively.
