[Laparoscopic antevasal uretero-ureteral anastomosis for treating retrocaval ureter].

The article presents a case of laparoscopic antevasal correction of the retrocaval ureter in a 16 year old patient, who was admitted to the hospital with complaints of aching pain in the right lower back. His history was noteworthy of early age onset of intermittent fever accompanied by abdominal and lumbar pain. Blood count and urinalysis were within normal limits, and he was treated symptomatically. However, no renal ultrasound scan was done. Intravenous urography and MSCT showed a retrocaval ureter. The diagnosis was confirmed by retrograde ureteropyelography. With the patient placed in the lateral position, the right ureter was mobilized by transperitoneal access, transected and mobilized from under the inferior vena cava. Anterior uretero-ureteral anastomosis on the stent was performed, drainage was established. The operating time was 90 minutes, blood loss was 60 ml. There were no postoperative complications. Drainage was removed 2 days after surgery and the patient was discharged for outpatient treatment. The stent was removed 6 weeks postoperatively. Control urography showed normal function of both kidneys, no urodynamic abnormality of the upper urinary tract was identified.

Retrocaval ureter and contra lateral renal agenesis – a case report and review of literature

ABSTRACT Associated congenital anomalies are seen in 21% of retrocaval ureter patients; among them, associated contralateral renal agenesis is a very rare entity. We report one such case of right circumcaval ureter with left renal agenesis, diagnosed after febrile UTI. Surgical correction with uretero-ureterostomy was successful. In literature very few such cases are reported and only one case with renal failure was reported. Unilateral renal agenesis cases complicated by associated such anomalies need definitive management and lifelong clinical monitoring to diagnose and prevent chronic kidney disease.
