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 ; 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 .
