A case report of congenital ureteral stricture: Obstructed, hydronephrotic solitary kidney with cystic dysplastic changes.

INTRODUCTION AND IMPORTANCE

Congenital ureteral stricture is a rare cause of antenatal hydronephrosis. Early diagnosis and treatment is important to prevent progressive loss of renal function.

CASE PRESENTATION

This is a case report a 5 month old infant with obstructed hydronephrotic solitary kidney detected during antenatal ultrasound. She was operated, and Intraoperative finding was proximal ureteric stricture and it was managed by pyeloplasty.

CLINICAL DISCUSSION

Congenital anomalies of the urinary tract and kidney are the leading cause of end-stage renal disease in children. Congenital ureteral stricture is commonly misdiagnosed as ureteropelvic junction (UPJ) obstruction preoperatively. The most common location for congenital ureteral stricture is the mid ureter, but there are a few case reports of congenital ureteral stricture occurring in the proximal ureter.

CONCLUSION

Ureteral stricture is usually associated with other urological anomalies such as, multi-cystic dysplastic kidney, mega ureter, and renal agenesis So diagnosis should not be delayed in such cases to prevent progressive loss of renal function, and end stage renal disease.
