Site-Specific Posterior Colporrhaphy and Perineorrhaphy for Rectocele
The patient is a 38-year-old female who presented with fecal incontinence, constipation, and stress urinary incontinence. She was found to have stage II posterior vaginal wall prolapse. She desired definitive surgical management of her prolapse and opted for posterior vaginal repair. Although stress urinary incontinence was demonstrated on urodynamic testing, the decision was made not to proceed with concurrent midurethral sling given her history of pelvic floor dyssynergia and intermittent urinary retention. The surgery was uncomplicated, and she was discharged on the day of surgery. Her recovery was unremarkable.
The patient is a 38-year-old G3P3 female with a history of celiac disease who presented to the urogynecology office with fecal incontinence, constipation, and stress urinary incontinence. She has a history of three vaginal deliveries, one of which was forceps-assisted. Her largest baby was 7 pounds 14 ounces.
The patient reported long-standing constipation since childhood that had worsened since her diagnosis of celiac disease. She was followed by the colorectal surgery service and was found to have a nonrelaxing puborectalis on electromyography (EMG), consistent with pelvic floor dyssynergia. She admitted to straining and using her digits to splint during defecation. She was started on a bowel regimen and was referred to pelvic physical therapy, which helped to decrease the straining. She also had symptoms of stress urinary incontinence that improved with pelvic floor physical therapy.
Her physical examination was consistent with stage II anterior and posterior vaginal wall prolapse. The posterior vaginal wall was at the hymen, and there was demonstrable rectovaginal pocketing. The anterior vaginal wall was 1 cm above the hymen. Apical support and total vaginal length were normal. The perineal body was normal; however, the genital hiatus was enlarged at 5 cm. See Figure 1 for a graphic demonstration of preoperative prolapse.

There was no indication for imaging for this patient.
She had urodynamic testing that showed stress urinary incontinence at a low volume, urgency urinary incontinence, and incomplete voiding. Based on her elevated postvoid residual, she underwent a renal ultrasound, which ruled out hydronephrosis.
Options for Treatment
Treatment of prolapse depends on the patient’s symptoms and goals. Options include expectant management, pelvic floor exercises, pelvic floor physical therapy, pessary, and surgical management (Figure 2). Because the patient found the prolapse bothersome, she declined expectant management and preferred to move forward with definitive surgical management.
Rationale for Treatment
The patient decided that she wanted a reconstructive surgery that was the safest and that would involve only her own tissues.
The patient had undergone urodynamic testing, which is most often performed preoperatively to assess for possible occult stress urinary incontinence that is a type of urinary incontinence that is “unmasked” by the prolapse repair. During the testing, the prolapse is elevated to simulate the repair and the patient is taken through various maneuvers to elicit stress urinary incontinence. If the patient has leaking during testing, she has a 58% chance of having urinary incontinence after the prolapse repair.1 There is a 38% chance that the patient may have leaking even if the testing is negative and may require a separate staged procedure to address the incontinence.1
Given the presence of pelvic floor dyssynergia on prior testing, presence of significant detrusor overactivity, and the improvement of stress urinary incontinence with pelvic floor physical therapy, the patient was advised not to proceed with concomitant midurethral sling at the time of prolapse repair. The patient agreed with the plan and understood that she may experience worsening urinary incontinence postoperatively.
The patient was taken to the operating room where general anesthesia was given, and a laryngeal mask airway was obtained. Sequential compression devices were placed on the lower extremities as venous thromboembolism prophylaxis and intravenous cefazolin was given as antibiotic prophylaxis. She was placed in the dorsal lithotomy position in candy cane stirrups. A timeout was performed with the entire operative staff. A Foley catheter was placed to drain the bladder.
The anterior vaginal wall revision was performed first. The area of anticipated dissection was injected with dilute 0.25% Marcaine with epinephrine. A transverse incision was then made at the level of the vaginal wall lappets, approximately 3 cm proximal to the urethra. The vaginal epithelium was then sparingly dissected off of the underlying pubocervical connective tissue and trimmed to remove the redundant vagina. The incision was then closed in a transverse manner with a running 2-0 Vicryl suture.
The posterior repair was performed next. A dilute solution of Marcaine with epinephrine was injected under the perineal skin and the posterior vaginal wall. The attenuated scarred perineal skin was excised. The posterior vaginal wall was dissected sharply off of the underlying rectum. The rectocele was then closed in a site-specific fashion; first, it was noted that the proximal edge and both lateral edges of the rectovaginal fascia had been detached. All sites were reattached with a running 2-0 PDS suture. Irrigation was performed, and excellent hemostasis was noted. Excess posterior vaginal wall was excised. The incision was closed with 2-0 Vicryl in a running stitch down to 3 cm above the hymen and held. Interrupted stitches of 0 Vicryl were placed to build up the perineal body and decrease the genital hiatus. The midline incision was then closed in a running fashion using 2-0 Vicryl suture. The perineum was closed with submucosal and subcutaneous interrupted stitches. A final rectal exam was performed, confirming that there were no stitches in the rectum and that there was good support to the anterior rectal wall and the perineal body. The vagina was irrigated, and hemostasis ensured. The Foley catheter was removed, and the procedure was deemed complete.
Approximately two hours after surgery, the patient underwent a backfill trial of void. The bladder was backfilled via the Foley catheter with 300 ml of sterile water. The Foley catheter was removed, and the patient was able to void more than 200 ml, thereby passing the trial of void. Subsequently, because she met all discharge criteria, she went home on the day of surgery.
The patient was seen two weeks after surgery. She was doing well and denied any vaginal bulge or voiding dysfunction.
