Introduction: Laparoscopic ureterocalicostomy is a useful alternative to laparoscopic pyeloplasty for treating ureteropelvic junction obstruction under certain conditions. One concern regarding this technique is the inevitability of amputation of the renal lower pole to expose the lower renal calyx.
Case Presentation: A 43-year-old man who presented ureteropelvic junction obstruction and multiple renal cysts underwent laparoscopic pyeloplasty, which could not be performed because of the intrarenal ureteropelvic junction. We switched the surgical technique to modified laparoscopic ureterocalicostomy, wherein amputation of the lower renal pole was substituted with fenestration of a renal cyst under the guidance of ureteroscopic light. Computed tomography performed 2 months postoperatively showed good patency of the anastomosis.
Conclusion: Light-guided laparoscopic renal cyst fenestration followed by ureterocalicostomy is feasible in patients with ureteropelvic junction obstruction and lower pole renal cysts adjacent to the lower renal calyx.

Background: Horseshoe kidney is the most common renal fusion anomaly, occurring in approximately 1 in 500 individuals worldwide. It is characterized by abnormalities in kidney position, rotation, and vascular supply. While often asymptomatic, horseshoe kidneys can lead to urological complications, primarily due to ureteric obstruction and impaired urinary drainage.

Background: Giant hydronephrosis as an rare condition is often caused by chronic ureteral obstruction. Nephroplication is a crucial procedure to improve urinary drainage in the kidney-sparing surgery for patients with giant hydronephrosis. However, traditional nephroplication via suturing kidney has technical difficulty and many potential risks.

Urinary tract dilations (UTDs) are the most frequent prenatal renal anomaly. The spectrum of etiologies causing UTD ranges from mild spontaneously resolving obstruction to severe upper and lower urinary tract obstruction or reflux. The early recognition and management of these anomalies allows for improved renal endowment prenatally and ultimately better outcome for the child.

Introduction: Prior analysis of children with grade 3 and 4 congenital hydronephrosis demonstrated that renal medullary pyramidal thickness (PT) is predictive of subsequent pyeloplasty (area under the curve [AUC] = 0.78). The objective of this study was to further analyze the utility of sonographic measurements including PT, anteroposterior pelvic diameter (APD), and renal length with an expansion of the number of infants with hydronephrotic kidneys including grades 2, 3, and 4 hydronephrosis.
