All are true about ureter except
Correct Answer: Penetrates the bladder wall without any valve
Description: Abdominal ureter The ureter is roughly 25-30 cm long in adults and courses down the retroperitoneum in an S curve. At the proximal end of the ureter is the renal pelvis; at the distal end is the bladder. The ureteropelvic junction usually coincides with the second lumbar veebra on the left, with the right being marginally lower. The ureter then continues anteriorly on the psoas major muscle, crossing under the gonadal vein at the level of the inferior pole of the kidney. The ureters course medial to the sacroiliac joint and then curve laterally in the pelvis. The colon and its mesentery are associated anterior to the ureters. Pelvic ureter The ureter enters the pelvis, where it crosses anteriorly to the iliac vessels, which usually occurs at the bifurcation of the common iliac aery into the internal and external iliac aeries. The ovarian vessels travel in the suspensory ligament of the ovary (infundibulopelvic ligament) and cross the ureter anteriorly and lateral to the iliac vessels. The ureters then course out to the ischial spines before coursing medially to penetrate the base of the bladder. The ureter enters the urinary bladder at posterolateral angles of the trigone of bladder, at the entrance, it is surrounded by the valve called the ureterovesical valve. Ref - Pubmed.com
