Blind-ending bifid ureter in a woman with urinary tract infection and a duplicated renal pelvis in her twin sister are reported. The blind-ending bifid ureter terminated as a fibrous cord with a terminal mass of immature renal tissue. This type of ureter may be a transitional form between histologically blind-ending bifid ureter and duplication of the renal pelvis and/or kidneys. Findings in twins support this opinion.

Blind-ending bifid ureter is one of the rarest congenital abnormalities of the genitourinary system. It can be symptomatic and can give rise to recurrent urinary tract infection and pain on the affected side. If there is any suspicion of this condition on the intravenous pyelogram, a retrograde ureteropyelogram should be done to demonstrate the blind-ending segment. In symptomatic cases, the condition can be treated successfully by exising the segment.

As documented with results obtained in 1685 patients the treatment of ureteric stones is today based on ESWL in situ and ureteroscopy with semirigid, ultrathin ureteroscopes and laser lithotripsy. All stones in the upper third of the ureter and larger stones in the distal third of the ureter are preferably treated with ESWL in situ whereas smaller stones in the distal ureter are better treated endoscopically. Midureteric stones remain the domain of primary ureteroscopy; with moderate obstruction in the asymptomatic patient it may also be acceptable to wait for the stone to pass into the distal ureter spontaneously to be treated by ESWL in situ there. Manipulating stones back into the kidney and treating them by ESWL there (pushback/ESWL) offers no advantage over ESWL in situ, as the results are similar, yet morbidity is higher. Blind instrumentation and open surgery have lost all justification.

Blind ending bifid ureter is a rare anomaly in the urinary tract. This anomaly may result from failure of a premature branch of the ureteral bud to join with the metanephric blastema. A 21-year-old man was admitted with macroscopic hematuria and colic pain in the left flank region. Urinalysis demonstrated hematopyuria and excretory urography suggested bifid ending accessory ureter with a stone on the left side. Surgical exploration showed that the accessory ureter was bifurcated from the left ureter at about 5 mm from the bladder wall and ran parallel with the left ureter. Although dense adhesions to the surrounding tissue existed, the accessory ureter was resected at the site of the junction. It measured 3 cm in length and 1 cm in greatest diameter. The stone found at the tip of the accessory ureter was composed of calcium oxalate (24%) and calcium phosphate (76%). Histological examination revealed that the ureter had all layers of normal ureteral structure and no renal tissue was identified in the specimen resected. During a follow-up period of 22 months after the operation, he was free of urinary tract infection and abdominal pain. Of 77 cases with blind ending bifid ureter reported in the Japanese literature, a ureteral stone was found in the blind branch in only 5 cases.

Blind-ending ureter is a well-recognized but rarely addressed abnormality that results in the urethral or bladder diverticulum. A girl and a boy are described with urethral diverticulum and bladder diverticulum, respectively, which are believed to be allied to blind-ending ureters.

Blind-ending bifid ureter is one of the most rare anomalies of the upper urinary tract. Three cases of blind-ending bifid ureter are reported. Case 1: A 53-year-old man was admitted with right lumbal colic pain. Kidney-ureter-bladder X-ray revealed the right ureteral stone and drip intravenous pyelography (DIP) revealed the left blind-ending bifid ureter. Case 2: A 61-year-old woman admitted with the complaint of asymptomatic microhematuria. DIP revealed extension of the right middle ureter and the left incomplete duplication of ureter. Retrograde pyelography revealed the right blind-ending bifid ureter. Case 3: A 57-year-old woman was admitted with asymptomatic microhematuria. DIP revealed the left blind-ending bifid ureter. We collected 68 cases of blind-ending bifid ureter reported in Japan including our own according to the definition of Culp.

Thirteen cases of blind-ending bifid ureter are analyzed. The diagnosis was made by intravenous urogram. The distribution of the anomaly according to age, sex, location, symptomatology, and radiological features are reviewed. Blind-ending bifid ureter is not an uncommon anomaly as is generally believed. It is the purpose of this paper to draw attention to and increase the awareness of their existence.

Blind-ending bifid ureter in a girl with urinary tract infection, and a blind-ending duplicated ureter in her younger sister are described. The embryology of this rare anomaly is briefly reviewed.

Blind-ending ureteral buds result from a more or less complete duplication of the ureter in which the development of one of the branches is arrested before reaching renal mesenchyma. These malformations are rare, and no more than one hundred cases have been reported. We report four new cases in children. All were studied because of urinary infection and cystogram was diagnostic. All patients were operated upon, the blind ureter was resected, and the remaining complete ureter reimplanted in three cases.

Blind-ending bifid ureters, as one type of duplications, are a rare congenital anomaly of the urinary tract. Occasionally they present with unspecific symptoms and require surgical intervention. This case of a blind-ending bifid ureter was associated with an intravesical ectopic orifice. Recurrent urinary tract infection necessitated excision of the blind branch and ureteroneocystostomy using the psoas-hitch technique.
