RIRS for Treatment of Stones in Congenital Anomalous Kidneys
Sponsor: Al-Azhar University
Summary
The anatomic renal abnormalities like altered spatial relations with adjacent organs, abnormal calyceal orientation, and anomalous vascular patterns make the active treatment of stones in the congenitally malformed kidney a great challenge for urologists. In this prospective study, the investigators will evaluate the outcome of retrograde intrarenal surgery (RIRS) with extracorporeal shockwave lithotripsy (SWL) for the treatment of stones in the kidneys with rotation or position anomalies.

Interventions
RIRS
The standard RIRS will be performed using a disposable flexible ureteroscope. Holmium: YAG laser will be used for stone dusting and fragmentation. If indicated, JJ ureteral stent will be placed at the end of the procedure.
SWL
Patients who underwent SWL at our institution in the past five years. According to (a) the type of renal anomaly (rotation, position, or rotation/position anomaly), (b) the size of the stone (±5 mm), (c) location of the stone (lower polar or non-lower polar), and (d) density of the stone (\>800 HU or ≤800 HU), matched cases will be selected for comparison.
