We have reviewed the complications and follow-up in 6 patients who underwent kidney transplantation with cutaneous ureterostomy. Four patients had tuberculosis, 1 myelomeningocele and another congenital stenosis of the posterior urethra. Cutaneous ureterostomy was performed by suturing the edges of the distal end of the ureter to the skin. The mean follow-up was 40.6 months (range 2-105). The patient and graft survival rates were 83.3% and 66.6% respectively during the 249 months of total follow-up. Significant bacteriuria and leukocyturia were constantly present and the incidence of urinary infection was 3.1 episodes/patient/year. The early complications of the stoma were partial necrosis in 1 case and haematoma in another. The most frequent late complication was stomal stenosis requiring periodic dilatation. A plasma creatinine of 61.88 to 114.92 mumol/l reflected good long-term graft function in the remaining patients. Terminal cutaneous ureterostomy is a simple technique with good long-term results.

A 30-year-old male patient without diabetes mellitus and tuberculosis was referred to our outpatient department for the purpose of further examinations of azoospermia. Transrectal ultrasonography revealed the bilateral calcifications of vas deferens. Kidney-ureter-bladder X-ray and computerized tomography revealed also the same findings. Seminal vesiculography revealed no obstructive sign of vas deferens. Histopathology of testes showed hypoplasia. Judging from these findings, we diagnosed the case as calcification of vas deferens associated with spermatogenic disturbance. Review of the 31 cases reported in the Japanese literature including our case was performed.

Tuberculosis stricture of the ureter is a process that may lead to loss of renal function if undiagnosed and untreated at the right time. Currently, tuberculostatic agents combined with steroids, and the possibility of recurring to endourological treatment, achieve a high success rate. Our experience with 4 cases is described. All cases were easily resolved with minimally invasive techniques and have remained stable at follow-up ranging from 2 1/2 to 6 years. In view of our good results, we advocate the use of this treatment modality.

We reviewed the efficacy of augmentation enterocystoplasty about 15 cases, based on technical modalities and intestinal loop used. There were 10 tuberculosis bladders, 2 bilharzial bladders, 2 interstitial cystitis and one neurogenic bladder. We used for bladder augmentation the sigmoid (7 cases), ileum (6 cases) and coeco-ileum (2 cases). Ureteroileoplasty is associated in three cases for large tuberculous ureteral stenosis, and reimplantation of ureter in the neobladder is realised in seven cases. The results with detubularized ileum were excellent. We observed in one patient persistence of dilatation of upper urinary tract after use of detubularized sigmoid. The results with use of ileocoecum are poor. We observed good results by using detubularized ileum, so we prefer this intestinal loop than the others. There was no significative difference between different detubularisation technics. Reimplantation of ureter inneobladder is indicated when there is terminal ureteral lesions.

Chyluria is the passage of chylus into urine resulting in fistulization through the lymphatic system and the urinary system. This rare condition is usually caused by filaria infestation or malformations, neoplasia or trauma. We report a case of a 18-year-old man. The patient presented milky urine which had appeared after angiography following minor leg trauma. Physical examination revealed asymmetry of the face and cutaneous dyschromia. Blood tests revealed hypogammaglobulinemia and altered CD4/CD8 ratio (0.6). Urine tests showed proteinuria (30 mg/dl), lipiduria (triglycerides 750 mg/dl) and density of 1025. Renal function was normal. Abdomen computed tomography and urography were normal. Cystoscopy revealed the presence of milky urine in the bladder and selective catheterization revealed that the origin was the right ureter alone. Ascendent pyelography did not reveal any malformation of the urinary tract; but after this the chyluria spontaneously disappeared. The patient was rehospitalized 3 months later for recurrence. Lymphography was then performed and revealed a dilated lymphatic network with minute lacunar images projecting into the right kidney. Chyluria again disappeared spontaneously and recurred sporadically over the next two years in a patient who remained in good physical condition. The etiology of chyluria in a patient without filaria infestation is problematic, particularly when the most common causes (tuberculosis, neoplasia, trauma) are excluded as in our case. The asymmetry of the face, together with cutaneous dyschromia and the presence of a subarachnoidea cyst in the right temporal region suggested our patient had multiple congenital malformations.

There are several therapeutic procedures for stenosis of the ureter. Ileal plasty is indicated in case of extended stenosis or those located in the pelvis when the poor quality of the bladder prevents use of a bladder flap. We report 6 surgical cases from 1977 to 1993, there were 4 women and 2 men, mean age 34 years. There was an inflammatory cause in 4 cases (tuberculosis or bilarziosis), retroperitoneal fibrosis in 1 case and idiopathic stenosis in 1. Radiographically, the stenosis was unilateral in the iliac area (3 cases), unilater in the pelvis (1 case) and bilateral and iliopelvic in 2 cases. Associated lesions included bladder injury with a small sclerotic bladder in 3 cases. Partial unilateral was used in 2 cases, bilateral U ileoplasty in 1 and ileouretero-cecocystoplasty in 3. Results were good in 5 cases with a follow-up from 2 months to 7 years. The patient with bilateral U ileoplasy without an antireflux procedure had massive bilateral reflux with renal failure and urinary infections. Ileoureteroplasty is indicated in case of extensive stenosis of the ureter. Results are good if an effective antireflux system is installed.

This article examines how the spectrum of responses of the ureter to inflammation is manifested in conventional radiography and to some extent in newer modalities, such as ultrasound, CT scan, and MR imaging. Common clinical entities are highlighted. The re-emergence of tuberculosis in the urinary tract and current information on infection with organisms are also discussed.

Tumors of the renal pelvis are rare neoplasms: their yearly incidence is 1.4 cases per 100,000 men and 0.6 cases per 100,000 women. The annual incidence of renal tuberculosis is 13 cases per 100,000 persons. The likelihood of both diseases occurring in the same kidney is extremely remote. We report on a case of ureter transitional cell carcinoma developed in a patient with tuberculosis stenosis of the same ureter, small retracted bladder and destruction of the opposite kidney. Total uterectomy, augmentation ileocaecocystoplasty and contralateral nephrectomy were performed. Literature is briefly reviewed and is underlined too the paradoxical simultaneous occurrence of transitional cell carcinoma and active tuberculosis infection, while the use of the bacillus of Calmette-Guerin is being advocated in the treatment of urotelial tumors.

The incidence of tuberculosis has risen in many parts of the world, and more attention is being focused on genitourinary tuberculosis (GT), the second most common extrathoracic form of tuberculosis. Although chemotherapy is the mainstay of treatment, ablative surgery as a first-line management may be unavoidable for sepsis or abscesses. In cases with hydronephrosis and progressive renal insufficiency caused by obstruction, renal drainage (by stenting or nephrostomy) must be performed immediately. In all other situations triple-drug chemotherapy should be undertaken for at least 6 months and stable conversion obtained before ablative or reconstructive surgery is planned. Nephrectomy or partial nephrectomy is indicated for nonfunctioning or poorly functioning kidneys, particularly if continuous flank pain or hypertension is present. Stenosis of the ureter usually can be managed by temporary stenting and adjuvant corticosteroid therapy. Today the indications for augmentation are rare, but bladder replacement may be combined with ureter replacement using segments of intestine.

Based on a series of 14 operated cases, the author describes augmentation of a fibrotic bladder and replacement of the stenotic ureter by an ileocaecal graft. The lesions were due to urinary tuberculosis. Good resumption of normal micturition was observed, with no cases of renal failure.
