There are many opinions about the physiopathology of urinoma, most of which are chronic ureteral obstruction resulting in pyelosinus back-flow, renal sinus extravasation with pyelolymphatic and pyelovenous back-flow by 35-40 cm [H.sub.2]O and/or more increase in intrapelvic pressure, and therefore the resultant perirenal extravasation (14).
Urological advantages include an easier puncture of the kidney which lies closer to the skin; a demonstrated decreased risk of colon injury [7]; a better descending drainage and retrieval of stone fragments, facilitated by the downward position of the Amplatz sheath; and a lower intrarenal pressure leading to smaller pyelovenous back flow and postoperative infectious risk [8].
