The surgery for carcinoma of the uterine cervix combined with radiotherapy, as carried out at present, includes a definite risk for the urinary tract. Not so much the immediate functional disorders, which always recede, except in rare cases of fibrous retracted bladder, but the lesions which occur in several varieties lead one to re-implant immediately the ureter. Fistulae and early stenosis (16 out of 1,500) should be treated in the same way. These late complications, such as obstruction (12 out of 1,500) raise de problem of their etiology. Usually they are due to recurrent carcinoma (9 out of 12), rarely due to pelvic fibrosis (3 out of 12). It is rare then for re-implantation to be possible. There remains either nephrectomy which is the simplest solution, or an urinary by-pass operation either using an ileal bladder or as a palliative measure, using a silastic prosthesis. Finally, the risk of advanced carconoma is without remedy, abstention from surgery may then be justified but one should, as far as possible, attempt to prevent these complications both from the surgical technical point of view and from the point of view of irradiation dosage.

Ureric function in five women undergoing Wertheim hysterectomy for carcinoma of the uterine cervix was assessed from intra-ureteric pressure recordings made with a new technique. No notable difference was found in frequency, rate or amplitude between the uretero-peristaltic waves recorded immediately before and after dissection of the ureter. In three cases, however, retro-peristalsis occurred and in two of them it persisted throughout the operation. The presence of retrograde peristalsis may indicate that the peristaltic activity of these ureters was disturbed by the operative manipulation. Ureteric stasis was also demonstrable by radiographic techniques in those cases in which retro-peristalsis occurred during the operation but not in those in which it was absent.

Abdominal ultrasonography was performed on a caprine doe with anorexia, dysuria, and a palpable abdominal mass. Ultrasonography of a large firm mass situated cranial to the pelvic brim revealed a distended urinary bladder, which was confirmed by a dynamic bubble study. The left kidney had a large anechoic renal medulla and dilated renal pelvis and ureter consistent with ureteropyelectasia. Necropsy confirmed the existence of hydronephrosis and hydroureter, as well as cystitis, pyelonephritis, and partial urinary tract obstruction. The cause of the obstructive uropathy was a mass of fibrous tissue that obliterated the uterine cervix and partially obstructed the urethra and left ureter. The cause was presumed to be a cervical trauma from dystocia and forced extraction of a kid, with subsequent chronic fibrosis.

1. Electrophysiological techniques were used to characterize responses of afferent fibers in pelvic nerve of adult, virgin female rats to mechanical or chemical stimulation of internal reproductive organs and to mechanical stimulation of other pelvic organs. 2. In an in vivo barbiturate-anesthetized preparation, pelvic nerve afferent fibers responded to a wide variety of mechanical stimulation applied to restricted regions of the vaginal canal, caudal uterus (body and cervix), bladder, ureter, colon, or anus. 3. Single-fiber mechanoreceptive fields were invariably confined to a single organ. Notably, responses could be evoked not only by gentle stimulation of the unit's receptive field directly on the organ itself, but also by stimulating the field indirectly with intense stimulation through the appropriate part of a contiguous organ. This innervation feature is consistent with the separability of pelvic organ functions under innocuous conditions but their confusion under noxious ones. 4. Receptive fields on the reproductive organs extended from the caudal edge of the vagina to the uterine body (including the cervix) but were most often located in the fornix (vaginocervical junction). Most units had no or low levels of spontaneous activity. Their responses to mechanical stimuli were usually slowly or moderately adapting and time-locked to the stimulus. 5. Fibers with vaginal receptive fields (including the fornix) responded best either to vaginal distension with a balloon or, more often, to a probe moving along the internal vaginal surface in a direction toward the cervix. They were observed most frequently during the proestrus stage of the rat's estrous cycle. These fibers, therefore, seem particularly suited for relaying information about stimuli that occur during mating. 6. Fibers with receptive fields on the uterine cervix and body responded best to static pressure and were observed less frequently than those with vaginal fields, regardless of estrous stage. They were, however, sensitized by hypoxia. In addition, irritation of the uterus increased the probability of observing them. These fibers, therefore, may exert their primary function during reproductive conditions different from those of virgin rats, such as parturition. 7. Response activity of most of the mechanoreceptive afferent fibers supplying reproductive organs increased as the stimulus intensity increased into the noxious range; i.e., into a range in which the stimulus momentarily produced ischemia at the stimulus site. In addition, in an in vitro preparation, pelvic nerve fibers responded in a dose-dependent manner to injections through the uterine artery of bradykinin (BRAD) as well as to other algesic chemicals, 5-hydroxytryptamine (5-HT) and KCl.(ABSTRACT TRUNCATED AT 400 WORDS)

The internal female genital tract is rarely involved in neurofibromatosis. This report details a case of diffuse neurofibroma with prominent Wagner-Meissner body differentiation involving uterine cervix and endocervix, vagina, and vulva. The urinary bladder, urethra, and one ureter were also extensively affected. The anatomic localization of the lesions in this case is consistent with segmental neurofibromatosis restricted to the distribution of the second, third, and fourth sacral nerves. Failure to consider the possibility of genitourinary involvement in neurofibromatosis, the potential for localized manifestations in the absence of other easily recognized stigmata, and the subtle histologic features in small tissue biopsies may cause difficulty in diagnosis.

Stricture of the ureter following irradiation therapy for cancer of the uterine cervix is observed in 0.2-2.8% of all patients. The incidence in the literature is reviewed. The etiology, anatomical localization, time of development and the diagnostic problems are discussed. Old and more recent methods of treatment are mentioned and two cases treated with JJ-catheters are reported.

The surgical technique for a new alternative to urinary diversion is described. The biocarbon conduit is an inert device implanted in the abdominal wall. Its inner end is anastomosed to the distal ureter, and the outlet is over the abdominal skin and connected to a collector tube into a urinary bag. Twenty implants were performed between March, 1980, and July, 1981. Seventeen patients had carcinoma of the uterine cervix, and 3 had carcinoma of the urinary bladder (age range 34 to 79 years). All had severe urinary tract infection, retrodilation, and were in poor general physical condition. Eight fistulas developed in the 20 implants.

We report on a patient with a fistula between the right common iliac artery and the distal right ureter who had undergone pelvic exenteration for carcinoma of the uterine cervix. The patient also had received prior radiation therapy and was being treated with an indwelling ureteral stent at the time the fistula developed. Diagnosis was made by an occlusive ureterogram and the lesion was treated successfully with embolization of the common iliac artery.

The authors report a new case of uretero-uterine fistula and on this basis review the 9 other publications devoted to this subject since 1971. In their own case, the diagnosis was based upon the clinical picture only : permanent flow of urine through the uterine cervix with persistence of normal micturation and left lumbar pain following a caesarian section. Uretero-pyelo-calyceal distension proximal to a low pelvic ureteric stenosis visible by IVU was confirmed by RUP which succeeded in opacifying only the final 3 cm of the ureter. Only peroperative opacification of the ureter showed the fistula tract with the uterus. This was successfully treated by uretero-vesical reimplantation into a psoas bladder. Review of the literature revealed the following points : --The ureter is damaged by blind haemostasis of bleeding at the lateral angle of the hysterotomy, most often on the left, as a result of dextrorotation. --Clinical features consist of the urinary fistula, pain and infectious complications with upper urinary excretory tract obstruction. --The ureteric lesion is situated very low down, between 2 and 4 cm above the ureteric meatus. --Uretero-vesical reimplantation into a tubular vesical flap or a psoas bladder ensures treatment when the kidney remains functional. --The prevention of such lesions may be summarised very briefly : beware of the ureter at the lateral angles of hysterotomy for caesarian section.
