Risk factor of postoperative adverse events among children with duplex kidney undergoing upper pole heminephrectomy:...

Area of Science:

• Pediatric Urology
• Surgical Risk Assessment
• Congenital Anomalies

Background:

• Duplex kidney is a common congenital anomaly.
• Upper pole heminephrectomy is a surgical procedure to treat complications associated with duplex kidneys.
• Postoperative adverse events can impact patient outcomes.

Purpose of the Study:

• To identify independent risk factors for postoperative adverse events in pediatric patients undergoing upper pole heminephrectomy for duplex kidney.
• To enhance preoperative risk stratification and surgical planning.

Main Methods:

• Retrospective analysis of clinical data from pediatric patients with duplex kidney who underwent upper pole heminephrectomy.
• Patients were categorized into groups based on the occurrence of postoperative adverse events.
• Multivariate logistic regression analysis was employed to identify significant risk factors.

Main Results:

• The presence of upper renal ureterocele was significantly associated with increased risk of adverse events (OR = 7.116, P = 0.042).
• Accessory renal artery supply to the upper kidney (Type and other types) also significantly increased the risk of postoperative adverse events (OR = 10.639, P = 0.016; OR = 3.644, P = 0.039).

Conclusions:

• Upper renal ureterocele and accessory renal arteries are independent risk factors for postoperative adverse events in pediatric patients with duplex kidney undergoing upper pole heminephrectomy.
• These findings highlight the importance of considering these anatomical variations in surgical planning and risk assessment.
