✦ Ureteral Obstruction Treatment

Laparoscopic Ureteroureterostomy

Q: What length of stricture can be treated laparoscopically?

Laparoscopic ureteroureterostomy is suitable for strictures up to 2 cm; longer defects require Boari flap or ileal substitution. Your consultant will provide specific guidance based on your individual clinical situation and recovery.

Q: How long does the DJ stent stay after ureteroureterostomy?

The stent is left for 4–6 weeks and then removed cystoscopically as a brief outpatient procedure. Your consultant will provide specific guidance based on your individual clinical situation and recovery.

Q: Is robotic assistance used for this procedure?

Robotic assistance improves suturing precision in the deep retroperitoneal space; outcomes are equivalent to standard laparoscopic technique. Your consultant will provide specific guidance based on your individual clinical situation and recovery.

Laparoscopic End-to-End Ureteral Anastomosis for Ureteral Stricture

What is Laparoscopic Ureteroureterostomy?

Laparoscopic Ureteroureterostomy is the minimally invasive end-to-end anastomosis of the ureter after excision of a short ureteral stricture segment. Through laparoscopic ports, the strictured segment is excised, ends spatulated, and anastomosed with fine absorbable sutures over a DJ stent. It is suitable for short mid-ureteral strictures where sufficient length is available for a tension-free anastomosis, providing excellent results with the benefits of minimally invasive surgery. The procedure is performed under general or spinal anaesthesia with a hospital stay of 2–3 Days. Success rates reach >90% in appropriately selected patients at experienced centres.

Patients with short ureteral strictures (less than 2 cm) in the mid or upper ureter where tension-free end-to-end anastomosis can be achieved laparoscopically. Patients must be adequately fit for anaesthesia and free from active systemic infection before proceeding.

How the Procedure Works

Port Placement & Ureteral Mobilisation

Laparoscopic ports placed; ureter identified and mobilised around the stricture.

Stricture Excision

Strictured segment excised with clear margins on both ends.

Spatulation

Both ureteral ends spatulated on opposite sides to create a wide anastomosis.

DJ Stent & Anastomosis

DJ stent placed across the anastomosis; anastomosis completed with absorbable sutures.

Drain & Closure

Drain placed; ports closed; patient mobilised early.

Who Needs This Treatment?

→Minimally invasive excision of short ureteral strictures.
→Over 90% patency rate at long-term follow-up.
→Smaller incisions and faster recovery than open ureteroureterostomy.
→DJ stent supports healing and prevents early stricture recurrence.
→Suitable for iatrogenic and inflammatory short strictures.
→Can be combined with robotic assistance for improved suturing precision.

"Laparoscopic ureteroureterostomy gives us open-surgery results through small port incisions. Excision of the strictured segment and precise spatulated anastomosis provides durable patency with minimal patient morbidity."
