Two boys with congenital periureteral bladder diverticula without vesicoureteral reflux but with severe hydronephrosis and ureteral obstruction are described. No bladder outflow obstruction was present. Urinary tract infection was the presenting symptom in both boys, and this is the most common presenting symptom of bladder diverticula. Diverticulectomy, ureteral tailoring, and reimplantation were performed. Three different mechanisms are proposed for the association of bladder diverticula and ureteral obstruction: compression of the extravesical ureter against the detrusor by the full, tense diverticulum, fibrosis resulting from peridiverticulitis, or primary hypomuscularity of the ureterovesical junction and distal ureter.

Upper urinary tract calculi can be difficult to diagnose and to treat. One has to be aware that there is a risk for the mother which is often not recognized in the long term. The authors describe 17 cases of pregnant women aged between 20 and 33 who were treated for calculi in the Urological Service in Poitiers. They were diagnosed at different stages of pregnancy and a few had a previous urological history. The women presented in different ways, several of them with urinary colic and 10 with urinary colic and fever. Urinary tract infection and septicaemia also occurred. Six patients passed the stones spontaneously. The rest had to be treated by some form of operation, either during the pregnancy or afterwards, including one case of a patient who had to have her kidney and ureter removed and another who had to have a kidney removed. One patient had to have an emergency caesarean section for fetal distress although she had had stone removed at the 20th week of pregnancy. It is not possible to know from this series the incidence of stones in the tract. Various theories of the formation of the stones, including the anatomical changes that occur in the urinary tract in pregnancy, are suggested and these include the hormonal theory of dilatation of the ureters as well as the mechanical theory of changes in the course of the ureters. There are also likely to be changes in the phosphocalcium metabolism. Pain in the lumbar and lower abdominal region is the most frequent symptom occurring in 90-100% of cases and urinary tract infection is common.(ABSTRACT TRUNCATED AT 250 WORDS)

The authors report their experience on the surgical treatment of 69 infants and children with pyelo-ureteral duplication. Urinary infection was the main revealing symptom (52 cases). Vesico-ureteral reflux was the major associated anomaly (39 cases) involving most often the lower pole ureter; the surgical correction of the reflux was performed according to the technique of Cohen with a favorable outcome in all cases. Because of poorly functioning and dysplastic upper renal segment, partial upper pole nephrectomy was performed in 8 among 12 cases of associated ectopic ureteral orifice and in 9 among 15 cases of associated ureterocele. A reimplantation of the ureter was made possible in 3 cases of ectopic ureteral orifice and in 5 cases of ureterocele with little corresponding renal lesions. With the experience of one neonate who died from septic shock following partial nephrectomy there were no other post-operative complications in this series.

This is a report on a case of blind-ending ureter. The patient was a 56-year-old female who had complained of a pain in the left flank. There was no urinary tract infection. Excretory urography revealed a left blind-ending bifid ureter. It was resected and the removed specimen was about 8 cm in length. Histologically, it had all layers of the ureteral structure, but no renal tissue was found. The post-operative course was uneventful. We collected 55 cases of blind-ending bifid ureters reported in Japan including our own and discussed the difference between blind-ending bifid ureter and ureteral diverticulum.

Ureteral diameters were estimated on films from intravenous urography in 194 children (100 boys and 94 girls) aged 0-16 years. Children with signs of urinary tract infection, calculi, obstruction, duplication or malformation were excluded. Films obtained without abdominal compression were used for measurements, including only ureters visualized over 50 per cent of their lengths. A good correlation was demonstrated between ureteral diameter and age (r = 0.69) and between ureteral diameter and the length of a segment of the lumbar spine (r = 0.73). The widest part of the ureter was most often located just above the crossing of the iliac vessels. The right ureter was slightly wider than the left one. No difference between boys and girls was noted. The results are in good agreement with those of others obtained at autopsy. Bearing in mind the possible physiologic variations, it would seem that measuring the ureteral diameter can be of value for a more objective differentiation between dilated and non-dilated ureters.

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.

Bifid and double blind ureters are two rare congenital anomalies of the upper urinary tract. Usually they are incidental findings. Occasionally, they are associated with urinary tract infection, but the symptoms are not specific. The key to diagnosis is a careful urethral cystoscopy and retrograde pyelogram. Asymptomatic patients without urinary tract infection require no treatment. When symptoms or infection are present, excision of the blind branch is required with antireflux reimplantation of the normal ureter if needed.

Excretory urography and cystography were done in 200 girls from less than 1 year to 14 years old with a history of urinary tract infections. In 147 girls (73.5 per cent) the excretory urogram and cystogram were normal. Reflux was demonstrated on voiding cystourethrography in 19.5 per cent of the patients. Only 3 patients were found to have a normal voiding cystourethrogram and a significant abnormal excretory urogram. In only 1 patient (0.5 per cent) was an abnormality (an ectopic obstructed ureter) identified, which was amenable to intervention. We conclude that in the evaluation of girls with urinary tract infection an excretory urogram is indicated only in the presence of vesicoureteral reflux.

A case of ectopic ureterocele is reported. A 2-year-old girl was admitted for recurrent episode of urinary tract infection associated with fever. IVP showed bilateral duplex kidney, although no excretion of dye was noted from the right upper kidney. IVP also revealed a large filling defect at the bladder neck which was diagnosed as ureterocele by cystoscopy. Cystography demonstrated VUR to the right lower kidney. A complete duplication of ureter with ectopic ureterocele on the right, and incomplete duplication of ureter on the left were found at operation. She underwent complete removal of the ectopic ureterocele and reimplantation of the right two ureters. Her postoperative course was uneventful, post-operative IVP revealed improvement of pyelography of the right lower kidney and cystography revealed no VUR.

Based on a personal series of 310 observations, the authors have studied the presenting signs, the etiology, the urinary bacteriology and the localization of the stone in children with urolithiasis. Urinary tract infection is the presenting sign in 55% of the cases, hematuria in 23% and abdominal pain in 20%. Urinary malformation is associated in 26% of cases, whatever the age at diagnosis. The urinary bacteria found in 55% of cases is Proteus. Localization was in the kidney in 228 cases, in the ureter in 71 cases, the bladder in 45 cases and in the urethra in 5 cases.
