A case of blind-ending bifid ureter is presented. A 65-year-old man was admitted with the complaint of dysuria. He had no past episode of left flank pain or pyelonephritis. Digital examination and urethrography suggested benign prostatic hypertrophy. Drip infusion pyelography showed an abnormal cavity at the lower portion of the left ureter. He was diagnosed as benign prostate hypertrophy and left blind-ending bifid ureter. During suprapubic prostatectomy, the bifid ureter was resectd. The related reports are reviewed in the Japanese literature.

A 63-year-old woman with the complaints of left renal stone and fistula between left ureter and colon was transferred to our clinic by a local doctor. Anemia, gamma-globulinemia, and acceleration of ESR were detected by hematology on admission. Kidney-ureter-bladder X-ray and intravenous pyelography showed left non-functioning kidney with coral stone, and RP revealed a fistula between left ureter and sigmoid colon. She was operated by nephroureterectomy and fistulectomy. The resected kidney appeared pale and parenchyma was almost replaced by yellowish tissue and pus. Histologically, the lesion was confirmed to be xanthogranulomatous pyelonephritis. Meanwhile, the cause of the fistula was considered to be due to extending ureteritis and pelvic infection from the pyelonephritis. Postoperative course was satisfactory.

Ectopic ureter is quite a rare malformation, and it can be more or less serious depending on its anatomy (monolateral or bilateral ectopy, duplicated ureter, single ureter) and the associated malformations. It's more common in female patients. Ectopic ureteral orifice can be either intravesical (bladder neck) or, more often, extravesical. Ectopia in women is more frequently found in the urethra and the vaginal vestibule; much less frequently in vagina and in uterus. In men it is mostly found in the posterior urethra; in the male genital tract is very rare. In most cases ectopic ureter is associated with pyelo-ureteral complete duplication: the upper kidney usually works badly or doesn't work at all, due to renal dysplasia or pyelonephritis. More rarely ureteral ectopia affects a single urinary system and can be monolateral or, in the most serious forms, bilateral. The main clinical signs are urinary incontinence accompanied by regular micturition (more exactly pseudoincontinence) in the female patients, and urinary infection. In the male there is no urinary incontinence. Authors report their experience about 54 ectopic ureters in 51 children. Treatment is always by surgery: the choice has to be made between conservative or radical attitude. 38 total exeresis of the ectopic excretory pathway (upper heminephroureterectomy or nephroureterectomy), 9 ureteral reimplantations, 1 uretero-pyeloanastomosis have been done. Outcome is always satisfactory in monolateral forms, more uncertain in bilateral forms with single ectopic ureter, due to incontinence and reduced bladder capacity problems and the possible associated renal failure.

We report a rare case of anomalous inferior vena cava (IVC) in a 46-year-old woman hospitalized for the examination of right hypofunctional kidney. She had no history of trauma or pyelonephritis and there were no abnormalities in laboratory findings except serum creatinine value. Excretory urography showed no excretion of contrast medium from right kidney and retrograde pyelography revealed moderate hydronephrosis of right kidney but the obstruction of the ureter was not recognized. Abdominal computed tomographic scan showed a total trace of IVC and inferior venacavography demonstrated complete obstruction of the IVC from its origin with collateralization of upper lumber veins and vertebral veins. Surgical exploration was performed and demonstrated that IVC was a trace from the postrenal segment to hepatic segment. Two right renal veins were draining into the upper lumber vein and the right ureter was compressed slightly by lower renal vein, dilated ovarian vein and fibrotic connective tissue.

Most human pyelonephritis Escherichia coli isolates express both mannose (MS)- and globoside (Gal-Gal)-binding pili. An ascending E. coli urinary tract infection model was established in the 16-wk-old female BALB/c mouse to compare the pathogenic significance of MS and Gal-Gal pili and their efficacy as vaccines for the prevention of pyelonephritis. The distribution and density of pilus receptor compounds in urogenital tissues and as soluble compounds in urine were determined with antibodies to the synthetic receptor analogues, alpha D-Gal(1----4) beta D-Gal and alpha D-Man(1----2) alpha D-Man. Both carbohydrates were detected in vagina, bladder, ureter, and renal pelvis epithelium and in collecting duct and tubular cells. A pilus receptor compound also was detected in urine. It competitively inhibited the binding capacity of MS pili and was found to be physically, chemically, and immunologically related to Tamm-Horsfall uromucoid. Infectivity and invasiveness were quantitatively and histologically characterized for four E. coli strains: J96, a human pyelonephritis strain that expresses both MS and Gal-Gal pili; two recombinant strains prepared from J96 chromosomal DNA encoding MS pili or Gal-Gal pili; and the nonpiliated K12 recipient. Intravesicular administration of J96 (10(6) colony-forming units [CFU]) resulted in renal colonization and invasion in each of nine mice. The Gal-Gal clone (10(6) CFU) colonized the kidneys in each of 10 mice but did not invade. In contrast, the MS clone (10(6) CFU) did not colonize renal epithelium or invade. This effect was superceded when larger doses (greater than or equal to 10(10) CFU) of the MS clone were administered in volumes that cause acute vesicoureteric reflux. The efficacy was determined of vaccines composed of pure MS or Gal-Gal pili or the lipopolysaccharide containing O somatic antigen of the challenge strain, J96. The Gal-Gal pilus vaccine blocked renal colonization in 19 of 22 mice and renal invasion in 10 of 11 mice. Gal-Gal pili may be useful immunogens for the prevention of pyelonephritis in anatomically normal urinary tracts.

Unilateral pyelonephritis was induced in 50 rabbits by injecting Escherichia coli (minimum inhibitory concentration of tobramycin 0.25 mg/l) into the left kidney and by obstructing the ureter temporarily. Tobramycin treatment (daily dose 10 mg/kg) was started 4 days after surgery, either in a single daily dose or in 3 divided doses at 8 h intervals, for 2, 3, 5, 7 or 10 days. Comparison of bacteriology, renal morphology, and renal functions (BUN, serum creatinine, alanine aminopeptidase, N-acetyl-beta-D-glucosaminidase, cathepsin B, sphingomyelinase) suggests better efficacy and renal tolerance of the single daily dose regimen in the treatment of experimental acute pyelonephritis.

Thirty-nine cases of functional reconstruction of exstrophied bladder are reviewed. There were 20 females and 19 males. In a first group of 31 staging was planned and carried out in 26 while 3 are awaiting a second stage. In a second group of 8 a single operation was performed. Out of the 31 early cases there were 2 deaths and 10 failures, 16 show good or very good functional result. All 16 show moderate renal scarring from reflux pyelonephritis which occurred between I and II stage. Single operation consisted of innominate osteotomy, bladder and bladder neck and urethral reconstruction and anti-reflux procedure (osteotomy was omitted in a 3 days old baby). Three, operated upon when aged 8 mths., 1 year and 4 years, were breakdowns of previous closure. They are incontinent and will need further surgery at the bladder outlet. Four are dry in the morning and suffer from occasional stress incontinence and enuresis. One, now aged 4 years, still wears pads. These last 5 are awaiting final assessment of and eventually further surgery to improve continence. In all 8 cases pyelo-calyceal cavities are normal except for a moderate right dilatation in one because of kinking of the reimplanted ureter. Delay in bladder closure (mean age 5 mths.) and severe changes to the bladder wall and possibly staging seems to be responsible for most of the failures and for renal damage occurring, after closure, in bladders showing moderate compliance. Single operation allows full protection of upper tract and kidney and should be preferred in patients aged over 2 months. Better functional results may be obtained if operation is performed soon after birth.

We have experienced 72 patients with primary vesicoureteral reflux (VUR) during the past 16 years. Sixty-five of them (100 ureters) were treated surgically to prevent reflux. Among the surgical methods employed, the Politano-Leadbetter method was the most frequent, being used in 56 patients (87 ureters). Other methods were the combined method in 2 patients (three ureters), the Glenn-Anderson method in 1 (2 ureters), the Cohen method in 1 (1 ureter) and the Lich-Gregoir method in 5 patients (7 ureters). As postoperative complications in the early stage (within 1 month after surgery), remaining VUR in 1 ureter in 1 of the patients who underwent surgery by the Politano-Leadbetter method and occurrence of VUR on the contralateral side in 3 patients with unilateral VUR were encountered. These conditions disappeared during the follow-up period. On the other hand, in the late postoperative stage, ureteral stenosis requiring further surgery occurred in 1 ureter in the transitional region to the urinary bladder in 1 patient 2 months after surgery by the Lich-Gregoir method. The rate of success was all 87 ureters (100%) for the Politano-Leadbetter method and 6 out of 7 ureters (85.7%) for the Lich-Gregoir method. The success rates for the other procedures were also good, resulting in an overall rate of 99 out of 100 ureters (99.0%). Ninety-nine percent of the patients had been treated at least once preoperatively for pyelonephritis or fever of unknown etiology. Among these patients, those who had had 5 or more such episodes accounted for 39%.(ABSTRACT TRUNCATED AT 250 WORDS)

Case report on a patient with an extensive dilatation of renal pelvis and ureter during the first and the following two pregnancies. Operative drainage was performed of renal pelvis on both sides in the 24th and 28th week of the first pregnancy. The second pregnancy ended with spontaneous abortion in the 27th week of pregnancy. Percutaneous punction nephrostomy with successful course of the third pregnancy. Drainage of renal pelvis by punction nephrostomy is indicated in case of co-existence between dilatation of renal pelvis and severe illness and destruction renal parenchyma and of septic pyelonephritis in pregnancy. This procedure should also be done in case of a solitary kidney and excessive dilatation of the renal pelvis. An operative approach is recommended in renal abscess.

A 66-year-old female with bilateral ureteral tumors associated with chronic renal failure is presented. She received pan-hysterectomy due to uterine cancer in 1957. She was first referred to our clinic to make internal shunt under a diagnosis of chronic renal failure. In 1979, the diagnosis of neurogenic bladder and bilateral vesicoureteral reflux (rt; grade 3, lt; grade 1) was made. She was admitted to our clinic with complaints of macroscopic hematuria and a temperature of 39 degrees C on April 28, 1983. Cystoscopically, pyuria from the right ureteral orifice was found. Right retrograde pyelography revealed severe dilatation of the right ureter and renal pelvis with some filling defects. For drainage of pus retaining in the right renal pelvis, right percutaneous nephrostomy was made under the guidance of ultrasonography. After her general condition improved, right nephroureterectomy was performed under the diagnosis of right pyonephrosis on June 8, 1983. Right pyelonephritis and right ureteral tumor, grade 3, were pathologically demonstrated. After the operation, an invasive bladder tumor was detected on cystoscopy and ultrasonography, subsequently a total of 3,900 rad irradiation was given to the bladder tumor. She died of pulmonary edema 7 months later. Autopsy demonstrated a transitional carcinoma, grade 3, of the left ureter. Bilateral urothelial tumors of the upper urinary tract is rare, and to our knowledge only 29 cases have been reported in Japan.
