The muscular layer of the wall consists of three layers of smooth muscle together referred to as the detrusor muscle. In a duplicated urinary tract the upper-renal moiety is associated with an ectopic ureter and this is thought to occur secondary to late ureteral budding from the mesonephric duct. The smooth muscle surrounding the calyces, renal pelvis, and ureters is of the syncytial type without discrete neuromuscular junctions. As the ureters enter the pelvic cavity they turn medially and cross in front of the common iliac bifurcation. Major calyx is the cavity formed by the convergence of several minor calyces, which drain urine from the minor calyxes into the renal pelvis then through the ureter.
