A text-book of clinical anatomy : for students and practitioners . hat portion of the ureter which liesabove the brim of the pelvis is called the abdominal portion, and isabout five inches in length. The portion between the brim of thepelvis and the bladder is called the pelvic portion. Its relation to themale and female genitalia will be described under The Pelvis. The average length of the ureter is about 30 cm. (12 inches), theleft being slightly longer than the right on account of the higher positionof the left kidney. The diameter of the ureter is not uniform; it pre-sents three contractions and two intermediate dilatations. The first con-traction is the narrowest portion of the ureter (Fig. 81), and is situatedabout 7 cm. {o.\ inches) below the hilum of the kidney. The secondcontraction, called the inferior isthmus, is at the angular bend at thefoot of the pelvis, and the third contraction is at its termination inthe bladder-wall. The two dilatations which lie between the threecontractions are frequently called the upper and the lower Fig. 93.—Specimen illustrating one of the causes of imperforate anus. S, Sigmoidflexure and descending colon, terminating in a blind pouch (R), corresponding to the rec-tum, which communicated by a slit-like opening with B, rudimentary bladder. K, , Dilated ureter. C, Clitoris. A, Dilated hollow viscus, communicating through a wideopening with B, bladder, and probably corresponding to the dilated urachus. 301 THE PELVIS IN GENERAL. 303 The former lies in the abdomen, the latter in the pelvis. The uretersconverge as they descend in the abdomen. The Pelvis in General. The pelvis is formed by the innominate bones and the is divided into the false pelvis, lying above the iliopectineal lines,and the true pelvis, lying below them. The false pelvis was takenup in connection with the iliac fasciae. The true pelvis has an inlet, orsuperior aperture, which is cordate in the male and more oval in thefemale. Th
