Best Hospital for Robot-assisted Vesicovaginal Fistula (VVF) Repair in Vizag

Robot-assisted Vesicovaginal Fistula (VVF) Repair

A vesicovaginal fistula (VVF) is an abnormal connection between the urinary bladder and the vagina, resulting in continuous leakage of urine into the vaginal canal.

Robotic-assisted VVF repair brings the precision of the da Vinci Surgical System to a procedure that requires meticulous dissection, tension-free tissue handling, and multilayer watertight closure within the confined pelvic space where surgical accuracy is critical.

Cutting-edge Surgical Innovations at CARE Hospitals

CARE Hospitals integrates advanced technologies to improve precision, safety, and surgical outcomes in VVF repair.

• da Vinci Robotic Surgical System: Provides high-definition three-dimensional visualisation and tremor filtration, enabling highly precise multilayer closure in the deep pelvic space.
• Fluorescence imaging: This intraoperative imaging technique helps delineate fistula margins and assess tissue vascularity before closure, reducing the risk of ischaemic repair failure.
• Intraoperative cystoscopy: Flexible or rigid cystoscopy is integrated during surgery to confirm fistula location, evaluate proximity to ureteric orifices, and verify watertight closure at the end of the procedure.
• Peritoneal, omental, or Martius flap interposition: The robotic platform facilitates placement of well-vascularised tissue between the bladder and vaginal repair layers, reinforcing closure and lowering recurrence risk.

Conditions Treated by Robotic-assisted VVF Repair

Doctors may recommend robotic-assisted VVF repair for:

• Post-hysterectomy VVF, the most common urban cause, resulting from bladder base or trigone injury during abdominal or laparoscopic hysterectomy
• Post-obstetric VVF caused by pressure necrosis following prolonged obstructed labour
• Post-radiation VVF following pelvic radiotherapy for cervical or endometrial cancer
• Post-caesarean section VVF due to bladder injury during lower uterine segment dissection
• Recurrent VVF following failed prior repair, where robotic-assisted visualisation is particularly useful in scarred pelvic tissue
• Complex VVF associated with concurrent ureteric involvement

Why is Robotic-assisted VVF Repair Necessary?

VVF rarely heals spontaneously. While very small fistulae identified immediately after injury may close with prolonged catheter drainage, established epithelialised tracts generally require surgery.

Untreated VVF can lead to:

• Continuous urinary incontinence
• Recurrent infections
• Skin breakdown
• Significant psychosocial consequences, including social isolation

The robotic-assisted approach is preferred over open surgery because it provides superior visualisation in the deep pelvis, allows precise layer-by-layer closure through small incisions, and enables faster recovery.

Types of Robotic-assisted VVF Repair Procedures

Robotic-assisted VVF repair procedures include:

• Robotic-assisted transabdominal (transvesical) repair: The bladder is opened, and the fistula is approached internally. The fistulous tract is excised, the bladder and vaginal defects are closed separately in multiple layers, and a peritoneal or omental flap is interposed between them.
• Robotic extravesical repair: The fistula is approached through the plane between the bladder and vagina without opening the bladder. The robotic system is used to develop tissue planes, excise the tract, and perform multilayer closure with flap interposition.
• Robotic repair with ureteric reimplantation: When the fistula involves or lies close to one or both ureteric orifices, the ureter is reimplanted into a healthy portion of the bladder wall during the repair.
• Robotic redo VVF repair: This technique is suitable for recurrent or previously failed repairs. The enhanced visualisation provided by the robotic platform is particularly beneficial in fibrotic and scarred pelvic tissue.

Pre-surgery Preparation

Careful preoperative preparation is essential to optimise surgical outcomes.

Doctors perform investigations to determine:

• Fistula location, number, and size
• Characteristics of the fistulous tract
• Relationship to ureteric orifices

These investigations may include:

• Cystoscopy
• CT urogram or MRI pelvis
• Vaginal examination under anaesthesia

Additional tests include:

• Urine culture to identify active infection
• Renal function tests including creatinine and eGFR
• Full blood count, coagulation profile, and blood grouping for surgical preparation

To minimise complications, doctors also recommend:

• Appropriate antibiotics to treat infections before surgery
• Optimisation of diabetes, hypertension, anaemia, and other comorbidities
• Elective repair timing at least three months after the causative event to allow inflammation to resolve; radiation-induced fistulae generally require a minimum delay of twelve months
• Fasting for six hours for solids and two hours for clear fluids before surgery

Robotic-assisted VVF Repair Procedure

The procedure generally includes the following steps:

• Anaesthesia and positioning: The surgery is performed under general anaesthesia. The patient is positioned in the dorsal lithotomy position. A urethral catheter and ureteric stents are placed cystoscopically before robotic docking when the fistula is located near the trigone.
• Incision and port placement: The surgeon makes three to four small 8–12 mm incisions in the lower abdomen for robotic port placement. The robotic cart is docked, and the surgeon operates from the robotic console while the assistant maintains access to the vaginal and perineal field.
• Pelvic dissection: The vesicovaginal plane between the posterior bladder and anterior vaginal wall is developed robotically. The fistulous tract is identified while maintaining direct visualisation of the ureteric stents.
• Excision and closure: The fistulous tract is excised, and the vaginal wall is closed in one layer. A peritoneal or omental flap is interposed between repair layers. The bladder is closed in two layers, and watertight closure is confirmed using saline or methylene blue testing.
• Closure: A pelvic drain is placed, ports are removed, and the incisions are closed. The urethral catheter remains in place for 10–14 days.

The total operative duration for robotic-assisted VVF repair is typically between 120 and 180 minutes.

Post-surgery Recovery

Recovery after surgery generally includes:

• Hospital stay: Patients usually remain in the hospital for two to three days following uncomplicated robotic-assisted VVF repair. The urinary catheter remains in place throughout admission.
• Catheter management: The catheter is generally maintained for 10–14 days. A cystogram is performed before removal to confirm complete watertight healing.
• Activity: Early mobilisation is encouraged from the first day after surgery. Patients should avoid heavy lifting and sexual intercourse for six weeks. Most patients can return to desk-based work within two to three weeks.
• Follow-up: Doctors may recommend cystoscopic review at six weeks. Upper urinary tract imaging at three months is advised when ureteric involvement was present.

Risks

Although robotic-assisted VVF repair is generally safe, potential complications include:

• Fistula recurrence
• Ureteric injury or obstruction
• Bladder dysfunction such as reduced capacity, overactivity, or voiding difficulty
• Urinary tract infection
• Haemorrhage
• Need for conversion to open surgery

Benefits of Robotic-assisted VVF Repair

The primary advantage of robotic-assisted VVF repair is superior visualisation within the confined deep pelvis. This allows precise dissection of the vesicovaginal plane, especially in scarred post-surgical or post-obstetric tissue.

Additional benefits include:

• Precise multilayer closure using fine absorbable sutures with wristed robotic instruments that replicate the dexterity of open surgery through small incisions
• Accurate identification of ureteric orifices, reducing the risk of ureteric injury during trigonal or paratrigonal fistula repair
• Less post-operative pain and faster recovery compared to open transabdominal repair
• Shorter hospital stay of two to three days
• Return to normal activities within two to three weeks
• Success rates comparable to open surgery

Insurance Assistance for Robotic-assisted VVF Repair

Robotic-assisted VVF repair is covered under most major health insurance policies. The insurance facilitation team at CARE Hospitals assists patients with coverage verification, pre-authorisation, and reimbursement-related queries.

Patients are encouraged to contact the insurance desk during the initial consultation to begin the pre-authorisation process promptly.

Second Opinion for Robotic-assisted VVF Repair

VVF is a life-altering condition that requires careful evaluation of both surgical timing and approach. CARE Hospitals, Visakhapatnam welcomes second-opinion consultations for newly diagnosed or previously failed repairs, including review of imaging studies, cystoscopy findings, and operative notes to provide an independent expert assessment.

Conclusion

VVF is a treatable condition, but the quality of repair, appropriate timing of surgery, and surgeon expertise are critical factors in achieving a successful outcome. A successful first repair offers the highest likelihood of permanent cure, whereas failed repairs significantly increase the complexity of subsequent procedures.

At CARE Hospitals, Visakhapatnam, the robotic-assisted VVF programme provides women across North Andhra Pradesh with access to advanced subspecialty fistula surgery within the city itself.
