Hydronephrosis and pyelonephritis were diagnosed in a 2-year-old Limousin bull. Salient historical and clinical observations included weight loss, anorexia, intermittent colic, polyuria, polydypsia, and an ammoniacal breath odor. Intravenous treatment with fluids and antibiotics did not induce a favorable response. An anomalous vas deferens was observed on postmortem examination. The vas deferens ended in a blind polyp that protruded into the lumen of the urethra. This polyp may have caused chronic intermittent obstruction, predisposing to the hydronephrosis and pyelonephritis.

Polypoid cystitis, pyelonephritis, and obstructive uropathy was found in a cow with hematuria, dysuria, and colic. The cow was treated with penicillin, multiple B vitamin supplementation, and isotonic sodium chloride. Polypoid cystitis, diagnosed in this cow by use of endoscopic examination, is a common response to chronic inflammation of the bladder and can lead to obstructive uropathy. Although endoscopic confirmation of this diagnosis may not always be feasible, recognition of corresponding clinical signs can allow timely, appropriate treatment.

In 201 women with pathologic course of pregnancy (161 women suffering from urinary tract infection, pyelonephritis and colic, 40 women with gestosis) the kidneys and the upper urinary tract were studied by means of ultrasonography. In 86% of the 161 women with colic, urinary tract infection and septic complications a dilation of the renal collecting system was found, in 39.4% of them a marked dilation (sagittal diameter of more than 15 mm). Frequency and grade of dilation have been uncreased from the first to the third trimenon, with a significant preference of the right side. In patients suffering from gestosis a lower frequency and grade of dilation was found. Pregnant women with a sagittal diameter of the pyelon of more than 15 mm should controlled more intensively prae and post partum, but the grade of dilation is not the only criterion of therapeutic strategies.

Placement of internal ureteral stents before extracorporeal shock wave lithotripsy of large stone burdens has decreased the incidence of post-extracorporeal shock wave lithotripsy colic, secondary endoscopic procedures and prolonged hospital stays. However, indwelling stents have an associated patient morbidity and intolerance. A telephone survey of 50 patients (average stone burden 28 mm.) who were discharged from the hospital after treatment with an indwelling internal polymer stent was performed with a standard questionnaire. Symptoms reported with in situ internal ureteral stents included gross hematuria (42 per cent), fever or chills (20 per cent), and persistent discomfort or pain in the bladder and/or flank (26 to 38 per cent). Of the patients 44 per cent reported moderate to intolerable discomfort that was relieved by removal of the stent. The degree of symptoms was not associated with stent composition, style or length, or the presence of a transurethral string. Five patients had premature migration or dislodgment of the internal stent and 4 reported episodes of obstructive pyelonephritis requiring removal of an impacted stent or endourological intervention. Internal ureteral stents placed before extracorporeal shock wave lithotripsy have an identifiable patient morbidity while indwelling and, therefore, they should be used judiciously according to the stone burden, renal anatomy and body habitus.

In contrast to the majority of renal calculi, in situ extracorporeal shock wave lithotripsy (ESWL) for upper ureteral stones is still controversial. Some centers recommend retrograde mobilization of the calculus into the renal pelvis prior to ESWL as a routine procedure (UC + ESWL). To evaluate the efficiency of in situ ESWL for upper ureteric stones, we initiated a prospective clinical trial. From July 1985 to January 1986, 122 patients presented with upper ureteral calculi, necessitating a total of 146 different procedures: 88 in situ ESWL; 31 UC + ESWL; 15 antegrade ureteroscopies (URS); 6 retrograde URS; 2 open surgery (ureterolithotomy, nephrectomy), and 4 patients were managed conservatively. Of all 99 patients treated at the lithotripter, 80 patients received in situ ESWL (no emergency case, no location problems): in 60 patients (75%) the stone could be disintegrated in one session; 8 patients (10%) required a second ESWL session due to partial fragmentation. Retrograde mobilization using a ureteral catheter or URS was necessary in 9 patients due to failure of in situ ESWL (11%) and, in only 3 patients, we had to remove the stone by antegrade URS (4%). In conclusion, 96% of all upper ureteric stones suitable for primary ESWL could be treated by a noninvasive (in situ ESWL) or minimally invasive (UC + ESWL) procedure. Therefore we recommend in situ ESWL for these calculi. Primary retrograde mobilization is only indicated in case of location problems (stone close to the spine, obesity, skeleton deformation) or emergency cases (colic, hydronephrosis). Antegrade URS should be performed if retrograde mobilization fails or in emergency cases (acute pyelonephritis, following percutaneous nephrostomy, after clinical stabilization). The rate of open surgery is below 2%.

A case report of a 26-year old woman on chronic hemodialysis for pyelonephritis who took 10 mg of norethisterone acetate daily for suppression of menstruation. 1 week before admission colic-like pains appeared in right upper abdominal quadrant which were relieved by spasmolytics. Laboratory parameters (except those related to renal insufficiency), physical examination, x-rays of chest, stomach and biliary tract showed no abnormalities. Sonography revealed various round space-occupying lesions in the lower liver lobe. Before further studies could be initiated and following a hemodialysis session patient died of an intrahepatic hemorrhage confirmed by ultra-sonic and CAT-scan. Autopsy showed a large hematoma with more than 700 ml coagulated blood which caused rupture of the right liver lobe. Round adenomas were found in both lobes. The relationship between oral contraceptives and primary liver adenomas in young women without previous liver disease has been reported in the literature since 1973. 200 cases were found in the literature since 1977. Although mostly estrogens are blamed for liver adenomas, in this case it was a pure progestogen preparation. In another study of women with primary liver adenomas only 1 in 100 women used a pure progestin contraceptive. A relationship between androgens or anabolic steroids has been found in a number of case reports in the literature. It can be assumed that both combination preparations with estrogen components, and pure progestin preparations play a similar role in the pathogenesis of benign liver tumors.

The purpose of this experimental study was to try to develop a continent appliance-free urinary diversion with a non-refluxing urinary reservoir to be emptied by intermittent catheterization. A reliable antireflux plasty can be performed only on the large bowel wall. Continence can only be achieved using small bowel. For these reasons an ileo-colic urinary reservoir was conceived and experienced in 20 beagle dogs of both sexes. The posterior wall of the reservoir is formed by an intestinal plate constructed with two ileal loops. Continence is achieved by intussuscepting the terminal ileum in a retrograde fashion into the reservoir for a distance of 5 cm, thus creating a competent nipple valve between the pouch and the ileostoma. The anterior wall of the reservoir is formed using a colonic plate obtained by dividing the excluded sigmoid colon at the antimesenteric border. A long submucuous tunnel is created in the colon in which to lay the ureter. Thus renal infection and chronic pyelonephritis are avoided. Continence of the stoma is both socially and economically acceptable and improves the quality of life.

A total of 25 patients at least 75 years old underwent continent urinary diversion via a modified Indiana Pouch during a 68-month period, 21 of these with simultaneous radical cystectomy or anterior exenteration. The preoperative medical conditions as well as the early and late operative morbidity and mortality are reviewed with a mean follow up of 27 months. Average age of patients was 78.5 years, and the mean age of survivors is 81 years. There were two early mortalities attributed to ileal gangrene with secondary sepsis and aspiration pneumonia. Postoperative complications (superficial wound infection, middle colic vein bleed, right ureteral leak, ileus) occurred in five patients, two of whom required re-operation. Mean hospital stay was 12.4 days and ranged from 9-20. There were only six late complications [ureteral stricture (3), small bowel obstruction (1), incontinence (1)] necessitating re-hospitalization and surgical intervention. Late infectious complications included recurrent urinary tract infections (3), pyelonephritis (2), and C. Difficile enterocolitis (2) all managed medically. In addition, 10 other patients have died, 9 from metastatic disease and 1 from intercurrent medical problems. Of the 13 remaining patients, 11 are disease free and all are continent with a mean follow-up time of 33 months. We conclude that continent urinary diversion via a modified Indiana pouch with radical cystectomy or anterior exenteration can be performed with minimal morbidity or mortality, even in an elderly population.

Every general practitioner has to deal with urologic emergencies. The most frequent illnesses are urinary retention, acute scrotum, priapism, macrohematuria, nephritic colic, obstructive pyelonephritis and pyonephrosis. Whereas urinary retention, as well as acute ureteric stone colic must generally be treated by the practitioner, the urologist must often be consulted in case of an acute scrotum or for priapism. Testicular torsion is one situation, where surgical treatment needs to be performed within 6 hours. Of utmost importance is his timely assistance with the obstructive pyelonephritis and pyonephrosis. These are initially often not recognized, especially because the first ultrasound examination of the intrarenal pyelone may not show a dilatation of the collecting system despite obstruction. If the adequate treatment with drainage and antibiotics is applied too late, this can result in serious and potentially lethal consequences.

According to various authors the frequency of inflammatory complications associated with the use of IUDs ranges from 2% to 8%. Gynecological surgery on account of purulent, inflammatory disease of the adnexa uteri associated with IUD use (4-7%), damaging the urinary bladder and the ureters, is not uncommon. At the urological clinic of Stavropol, Russia, a total of 64 women who were in the 18-64 year age range, had urological complications, and had worn IUDs for 6 months to 14 years were observed. 34 of them presented with acute pyelonephritis attacks, 29 of them with renal colic and acute pyelonephritis, and 26 with renal calculi. In 22 women the acute pyelonephritis attacks were treated with antibiotics and uro-antiseptics. 19 of the 29 women who had renal colic and acute pyelonephritis underwent catheterization and drainage of the renal pelvis, and all of them passed fine kidney stones after the removal of their catheters. Urethral catheterization and drainage of the renal pelvis were performed in 31 patients in order to arrest renal colic and acute pyelonephritic attacks. The catheters stayed in for 2-3 days. For all these women removal of the IUD was recommended. 1 patient underwent ureterolithotomy. 8 patients rejected the removal of the IUD and had recurrent renal colics and acute pyelonephritis attacks. Removal of the IUD arrested pyelonephritis and lithogenesis in the kidneys. In 1 case of IUD removal injury to the uterine cervix and urinary bladder occurred, resulting in a vesicovaginal fistula. The report concludes with the case of a 44-year old patient who had worn a plastic IUD for 14 years.
