Open Heminephrectomy in Unilateral Duplex Collecting System and Complete Ureteral Duplication with Poorly Functioning Upper Pole: A Case Report

Aim: We report the results and experience of the Moewardi Hospital to do Physical Examination with Narcose and Heminephrectomy For Surgical Treatment Procedures Double Collecting System

Materials and Methods: Reported a 2 years old girl with double collecting system ren right with hydronephrosis upper moiety right (minimal function) + dextra hydroureter + ureterocele dextra and diagnosis of complications of chronic cystitis ureter and UK fitted. Furthermore, retrograde pyelography (RPG) was performed to obtain information on which ureteral estuary originated from superior moiety (pole) and inferior renal moiety as well as evaluation of whether or not a per-endoscopic incision was required and the boundaries of the area to be heminephrectomy. Furthermore, a heminephrectomy was planned in the upper moiety right area.

Results: Radiological examination is known to have a role in determining the presence or absence of ureteral duplication and can be done since the prenatal period. Ultrasound examination at about 20 weeks of gestation can detect the presence or absence of abnormalities in the fetal urinary tract. superior polus heminephrectomy in a system with duplicated malfunctioning, through laparoscopic ureteric ligation, or ureteral reimplantation if renal function remains good is the best management in children or patients with symptoms to resolve symptoms such as incontinence, prevent complications and maintain renal function.

Conclusion: The double collecting system is a form of congenital abnormality of the urinary system. Radiological examination is known to have a role in determining the presence or absence of duplication of the ureter and can be done since the prenatal period. Management is carried out based on the symptoms experienced by the patient and by looking at kidney function. Ureteroneocystostomy is the definitive surgical management of vesicoureteral reflux caused by ureteral duplication. If there is a case of a double collectivus system and with an ectopic ureter, then the procedure that can be given is a distal ureteroureterostomy through a laparostomy on a double J stent.
