Best Hospital for Robot-assisted Ureteric Reimplantation Surgery in Vizag

Robotic-assisted Ureteric Reimplantation

When the lower ureter becomes damaged, obstructed, or abnormally connected due to surgical injury, ureteric stricture, vesicoureteric reflux (VUR), or congenital anomalies, normal urine drainage is disrupted. This can place the affected kidney at risk of progressive and irreversible damage.

Ureteric reimplantation is the surgical procedure that detaches the affected ureter from its abnormal or diseased insertion point and reconstructs a new, properly positioned, anti-reflux connection to the bladder.

Robotic-assisted ureteric reimplantation uses the da Vinci Surgical System with magnified 3D vision and articulating instruments to perform this reconstruction with precision in the deep pelvic space, where accurate anastomosis is essential for long-term urinary tract function.

Why Choose CARE Hospitals, Vizag for Robotic-assisted Ureteric Reimplantation?

Ureteric reimplantation is one of the more technically demanding procedures in reconstructive urology. The repair must be tension-free, preserve the ureter’s blood supply, and create a correctly tunnelled anti-reflux connection through the bladder wall.

CARE Hospitals, Visakhapatnam combines experienced robotic urological surgeons with expertise in ureteric reconstruction, supported by multidisciplinary specialists in paediatric urology, nephrology, and interventional radiology for comprehensive pre-operative planning and post-operative follow-up.

The robotic platform enables these complex reconstructions to be performed through small port incisions in both adults and children.

Cutting-edge Surgical Innovations at CARE Hospitals

At CARE Hospitals, surgeons utilise advanced robotic surgical technologies to improve precision and outcomes.

• da Vinci Robotic Surgical System: Enables precise uretero-vesical anastomosis and anti-reflux tunnel creation within the confined pelvic space using enhanced 3D visualisation and wristed instrumentation.
• Real-time intraoperative cystoscopy: Used during surgery to confirm correct intravesical ureteric positioning, assess anti-reflux tunnel length, and verify the absence of ureteric kinking following reimplantation.
• Psoas hitch and Boari flap techniques: These advanced reconstructive methods help bridge longer ureteric defects without tension.
• Double-J stent placement: A Double-J stent is placed under direct robotic vision across the new anastomosis to support healing and reduce the risk of early stricture formation.

Conditions Treated by Robotic-assisted Ureteric Reimplantation

Doctors may recommend robotic-assisted ureteric reimplantation for:

• Vesicoureteric reflux (VUR), where urine abnormally flows backward from the bladder into the ureter and kidney, causing recurrent infections and renal scarring. Primary VUR in children is the most common paediatric indication
• Ureteric stricture at the ureterovesical junction caused by previous surgery, radiation, endoscopic procedures, or impacted calculi leading to obstructive uropathy
• Iatrogenic ureteric injury occurring during hysterectomy, anterior resection, caesarean section, or urological surgery
• Ureterocoele, a balloon-like dilatation of the intravesical ureter causing urinary obstruction
• Ectopic ureter opening into an abnormal location such as the urethra or vagina
• Post-radiation ureterovesical stricture resulting from pelvic radiotherapy-induced fibrosis
• Vesicovaginal fistula (VVF) repair involving one or both ureteric orifices

Why is Robotic-assisted Ureteric Reimplantation Necessary?

Abnormalities at the ureterovesical junction create back-pressure on the kidney. In VUR, infected urine repeatedly reaches the kidney during bladder contractions, causing pyelonephritis and progressive renal scarring. In obstructive conditions caused by strictures or injuries, hydronephrosis and declining renal function may develop.

Although antibiotics and temporary stenting may provide short-term management, they do not correct the underlying anatomical problem. Definitive reconstructive surgery becomes necessary when infections persist or kidney function is threatened.

Types of Robotic-assisted Ureteric Reimplantation Procedures

Different robotic-assisted ureteric reimplantation techniques include:

• Robotic Cohen cross-trigonal reimplantation: The ureter is detached from its original opening and reimplanted across the posterior bladder wall to the opposite side, creating a long anti-reflux submucosal tunnel. This is most commonly used for primary VUR in children.
• Robotic Lich-Gregoir extravesical reimplantation: An anti-reflux tunnel is created externally on the bladder wall without opening the bladder. The ureter is placed within the tunnel, and the detrusor muscle is closed over it. This approach is commonly preferred in adolescents and adults.
• Robotic psoas hitch reimplantation: For mid or lower ureteric defects, the bladder is mobilised and attached to the psoas tendon to bridge the distance between the shortened ureter and bladder.
• Robotic Boari flap reimplantation: For longer ureteric defects where a psoas hitch alone is insufficient, a flap of bladder wall is tubularised to create additional length before the ureter is attached. This requires a healthy and adequately capacious bladder.
• Robotic ureterocoele repair and reimplantation: The ureterocoele is incised, and the affected ureter is reimplanted into its correct anatomical position.

Pre-surgery Preparation

Before surgery, doctors may perform the following investigations:

• Renal ultrasound to assess hydronephrosis and cortical thickness
• Voiding cystourethrogram (VCUG) to confirm and grade vesicoureteric reflux
• Nuclear medicine renogram (DTPA/MAG3) to evaluate differential renal function and drainage
• CT urogram or MRI urogram to assess ureteric anatomy, stricture level, and bladder capacity for planning psoas hitch or Boari flap procedures
• Urine culture to detect active infection
• Renal function tests including creatinine and eGFR
• Complete blood count and coagulation profile for surgical readiness
• Paediatric anaesthetic assessment with age-appropriate fasting and fluid management protocols for children

Robotic-assisted Ureteric Reimplantation Procedure

The procedure generally includes the following steps:

• Anaesthesia: General anaesthesia is administered, and the patient is positioned supine or in a modified Trendelenburg position.
• Incision and port placement: Three to four small incisions are made in the lower abdomen for robotic instrument insertion.
• Ureteric mobilisation: The ureter is carefully identified and dissected free from surrounding tissues while preserving its blood supply. Adequate length is ensured for tension-free reconstruction.
• Bladder preparation:
  • Extravesical approach: The detrusor muscle is incised to create a tunnel without opening the bladder
  • Intravesical approach: The bladder is opened, and a tunnel is created across the trigone
  • Psoas hitch or Boari flap: The bladder is mobilised or a bladder flap is created to bridge larger ureteric defects
• Anastomosis: The ureter is reattached to the bladder using fine absorbable sutures. A Double-J stent may be inserted across the anastomosis to support healing.
• Closure: A surgical drain is placed, robotic instruments are removed, and the small incisions are closed.

The procedure usually takes between 90 and 180 minutes.

Post Surgery Recovery

Recovery after robotic-assisted ureteric reimplantation generally includes:

• Hospital stay: Most uncomplicated cases require a hospital stay of two to three days. More complex reconstructions such as Boari flap procedures may require an additional day.
• Catheter management: The urethral catheter is typically maintained for five to seven days and removed once pelvic drain output becomes minimal.
• Double-J stent removal: The internal ureteric stent is removed cystoscopically four to six weeks later as an outpatient procedure.
• Activity: Mobilisation begins from the first day after surgery. Strenuous activity should be avoided for four to six weeks. Most patients return to desk-based work within two weeks.
• Follow-up: Ultrasound is usually performed at six weeks, followed by renogram or VCUG at three to six months to confirm adequate drainage and resolution of reflux.

Risks

Potential complications include:

• Anastomotic stricture or narrowing
• Persistent vesicoureteric reflux
• Ureteric obstruction
• Urinary leakage from the anastomosis
• Haemorrhage
• Bladder dysfunction such as urinary frequency, urgency, or bladder spasms related to bladder incision or stent irritation

Benefits of Robotic-assisted Ureteric Reimplantation

The primary advantage of robotic-assisted ureteric reimplantation is precise anti-reflux tunnel construction through small incisions.

Additional benefits include:

• Magnified 3D visualisation for accurate uretero-vesical suturing and submucosal tunnel creation
• Reduced post-operative pain and bladder spasm compared to open intravesical surgery
• Shorter hospital stay of two to three days
• Faster return to normal activities, usually within two to three weeks
• Suitability for both paediatric and adult patients
