Congenital mid ureteric valve (MUV) stenosis is a very rare cause of ureteric obstruction and hydronephrosis (HN) in children. We describe how we manage laparoscopically one case of a patient with congenital MUV. We describe a 6-month-old boy born with antenatal left HN, with an anteroposterior diameter (APD) of 1,5 cm. Follow-up renal ultrasound at 3 months of age showed an increase in left kidney HN, approximately 2.5 cm below the PUJ associated with distal stenosis. Renal scintigraphy with DTPA showed an obstructive pattern. Urography scan showed an abrupt reduction in the caliber of the mid left ureter Based on a preoperative diagnosis of MUV stenosis, we performed a laparoscopic left ureteroplasty. Abrupt tapering of the left ureter at 3 cm from the PUJ was identified. Proximal ureter repair was performed before the resection of the narrowing segment. The two edges of the ureter were spatulated and continuous anastomosis was performed without tension. An antegrade JJ stent was inserted after the posterior part of the anastomosis was done. Patient made an uneventful recovery and was discharged on the first postoperative day. Laparoscopic ureteroplasty is a complex but feasible option to treat patients with congenital MUV stenosis.

Strictures of the ureter may occur from iatrogenic injury or impacted kidney stones. Complications from ureteroscopy may result in ureteral stricture in 0,5-2% of patients. New techniques are being described in order to minimize the morbidity associated with classic approaches. This is a step-by-step video of this novel technique: a successful laparoscopic ureteroplasty with gonadal vein graft for a iatrogenic long ureteral stenosis. A 16 year old female patient, with multiple previous ureteroscopies for ureteral stones, presented with severe left lumbar pain. An abdominal CT and a pyelography were performed showing a 3 cm left mid-proximal ureteral stricture with proximal hydronephrosis. The stenotic area was identified and an anterior left ureteral incision was made. Gonadal vein was removed and prepared, being sutured in the anterior surface of the ureter. Patient was discharged in the second post operative (PO). JJ stent was removed after 1 month. A 3 month PO pyelography was performed, showing no fistula and resolution of the stricture. Twelve months after surgery, the patient was painless with symptom resolution. The use of gonadal vein as a graft for ureteral strictures is a new possible approach, although more cases are necessary to evaluate its results.
