Currently, the most favored surgical procedure used to restore normal peristalsis to massively dilated adynamic ureters is ureteral tailoring. This procedure, however, seriously jeopardizes the ureter's blood supply and frequently results in ischemia with ureteral stenosis and further renal deterioration. To preserve the distal ureter's vasculature a new technique of reducing ureteral caliber and restoring normal peristalsis with minimal disruption of the blood supply was developed and performed in 14 dogs with excellent results.

Megaureter is the descriptive term applied to the large, wide, dilated and often tortuous ureter, which is usually congenital. Megaureter may result from a number of causes and an accurate diagnostic classification, such as refluxing, obstructed or non-refluxing, non-obstructed, is essential for appropriate management. The 52 consecutive patients with the various forms of megaureter presented typify the various causes of the entity. Surgical intervention virtually is universal and factors bearing upon recoverability and prognosis have been analyzed.

A case is presented in which massive uterine hemorrhage in early pregnancy is successfully controlled by bilateral uterine artery ligation. A 26-year-old white woman, gravida 3, para 1, abortus 2, was admitted 8 days following an elective abortion because of heavy bleeding and a low grade fever which failed to respond to Ergotrate and tetracycline. Although bilateral ligation is not the answer to all problems of bleeding from the uterus, it is superior to most other procedures, and physicians providing obstetric care should be familiar with the technique. The vessels can be easily identified, and the ureter and bladder are outside of the operative field. Although bleeding may continue from ovarian collateral vessels, the success rate is 90% with most of the failures being associated with placenta previa or placenta accreta. There are no short or long term complications.

A case of ureteral obstruction from bypass surgery is presented with review of the literature. A pathogenesis for the obstruction has been suggested and specific treatment recommended. More importantly, however, a plea is made to place the ureter anterior to the graft and to study the patient both pre- and postoperatively to prevent obstruction of the ureter in these patients.

A 13 years old boy with a 2 year history recurrent rightsided epididymitis was found to have an ectopic orifice of the vas deferens opening into the distal part of the left ureter of a hypoplastic left kidney. Because of possible interference with fertility vasovesiculography was not done. Therefore it could not be identified whether the vas deferens was of right or left sided origin. The genesis of this extremely rare malformation is discussed.

Respect and knowledge of and for the ureter should be in every surgeons armamentarium. An intravenous pyelogram should be done in selected cases for precise definition of the location and nature of any pathologic or anamolous condition of the ureters.

A study was made of 32 cases of single ectopic ureters (without duplication) to assess the abnormalities observed in the corresponding renal parenchyma and to correlate renal status with location of the ectopic uretic opening. Specimens were obtained from 26 nephrectomies and renal dysplasia was found in 22 cases. There was a close relationship between renal anomalies and location of the ureteric opening. The more remote the ectopic orifice from its normal position, the more severe were the associated renal lesions. Dysplasia was always present when the ectopic ureter opened outside the urinary tract (vagina, Gartner's duct, vestibule, seminal tract). Am embryological concept is proposed to explain the association of renal dysplasia with abnormal location of the ureter opening. It is based on the abnormal--premature or late--appearance of the ureteral bud on the Wolffian duct resulting in the abnormal positioning of the bud on the Wolffian duct with the ureter growing into nephrogenic tissue lacking the potential for normal renal development and leading to renal dysplasia.

A prospective study was begun to determine the role of non-efflux as a factor in the etiology of vesicoureteral reflux. Fifteen patients who had had 1 kidney removed for reasons other than reflux were available for study. Voiding cystourethrograms were done in all 15 cases to ascertain whether the remaining defunctionalized ureter was subject to reflux. In no instance was reflux demonstrated into the non-effluxing ureter.

The circumstances surrounding the treatment of a primary high grade invasive transitional cell carcinoma occurring in the ureter of a solitary kidney indicate that the combination of surgery and radiation therapy occasionally may be markedly effective for controlling this generally lethal disease.

Urinary tract infection, obstruction and fistulation are the three commonest urological complications following radical treatment of cervical carcinoma. Special trends in treatment are discussed. Long-term results confirm the value of using a bladder flap in cases of reimplantation of the ureter into the bladder. Formation of a unilateral or bilateral "psoastip-bladder" (bipartition of the bladder) is described and active surgical management is recommended in cases of operable recurrent cervical carcinoma involving the urinary tract.
