Stone in Uretrocoel with duplex renal system.
👉The Weigert-Meyer law, also known as the Meyer-Weigert rule, describes the typical anatomical relationship of ureters in a duplicated renal collecting system. In cases of complete ureteral duplication, where two ureters drain the same kidney, the lower pole ureter typically inserts into the bladder in a normal, or orthotopic, position, while the upper pole ureter inserts more inferomedially and often ectopically, potentially leading to obstruction or other issues.
