A non-functional and permanently damaged lower urinary tract is no longer a contraindication to kidney transplantation. In patients with this disorder the ureter commonly is drained by an intestinal conduit. We have used terminal loop cutaneous ureterostomy as a method of urinary drainage in 3 patients with cadaver kidney transplants who have been followed for up to 8 years. The technique of terminal loop cutaneous ureterostomy and a report of these cases are presented.

Three children with ectopic ureteroceles were examined with ultrasound, intravenous urography and cystography. In all cases the ultrasound studies outlined the ectopic ureterocele within the fluid-filled bladder and in one case added additional information regarding the non-functional portion of the duplication and its ureter.

Double ureters are not a rare anomaly. In the great majority of duplex-ureter systems, both components are functionally normal. Some may present medical problems such as abdominal cystic masses and recurrent urinary tract infections, even from the newborn period. The choice of the best method of the operation depends on residual renal function, the form of ureters, the shape and the position of the ureter orifice, and other factors. So, there are many methods by which to operate on duplex-ureter systems. Total heminephroureterectomy may be the best method of choice, if the duplex-ureter portion is non-functional. It is however, very difficult to resect the pathological ureter with the mate ureter uninjured, when the mate is covered by a common sheath or the patient is very small. Recently, two patients were admitted to our hospital because of abnormal findings of intrauterine echogram. One of them had a large ureterocele with a dilated ureter whose upper pole duplex kidney was non-functioning and cystic. The other patient had an upper ureter orifice opening ectopically to vagina, a ureter dilated, and a non-functioning upper ple duplex kidney. For heminephroureterectomy, resection of the upper one-fourth of the upper pole ureter was easy. But further excision of ureter seemed threatening to the mate ureter. We applied the mucolysis method, which we had been using as the operation of Sowve's method for the patients with Hirschsprung diseases. The method was technically easy and safe. There have been no complications after 1 year of follow up.

A 69-year-old man was admitted for further examination of right hydronephrosis in November 1988. Radiologically, excretory urography showed right non-functional kidney and antegrade pyelography revealed filling defect of right renal pelvis and ureter. Cytology findings of right renal urine indicated transitional cell carcinoma. Computed tomography revealed multiple mass of liver. The patient was administered M-VAC (methotrexate, vinblastine, doxorubicin and cisplatin) combination chemotherapy. After the 4 courses of treatment, the mass of the primary lesion and hepatic metastasis disappeared and he achieved complete remission. The side effects noted were mild myelosuppression, alopecia and gastrointestinal symptoms such as nausea and vomiting.

A 49-year-old female presented with a low abdominal tumor. Before operation, she had neither evidence of androgen excess nor abnormal tumor marker values, but US, CT and MRI findings strongly suggested the possibility of a malignant ovarian tumor. Her operative findings were as follows: a goose egg-sized main tumor in the low abdomen, with a walnut-sized tumor in the right side, which grew around the right ureter, causing right non-functional kidney. Pathological examination revealed her tumor was a very rare type of malignant Sertoli-Leidig cell tumor with pelvic lymph nodes metastases. Most patients with this disease usually have good prognoses, but with metastasis or recurrence, no therapy is as effective as in epithelial ovarian cancer. In this case, we selected a new combination chemotherapy of CBDCA, Etoposide and Epirubicin, considering current changes in the chemotherapy for ovarian germ cell tumors and Sertoli-Leidig cell tumors of testis. Now, 1 year and 4 months after operation, she has no evidence of recurrence or metastasis. This study proposes a new, presumably more effective chemotherapy for an ovarian malignant Sertoli-Leidig cell tumor.

The ultrastructural interaction between multinucleate giant cells (MGCs) and the Schistosoma haematobium eggs is described at the transmission electron microscopy (TEM) level, in granulomas of the lower ureteral segments of Saudi patients. The MGCs were found only within the parasite empty egg-shells which were embedded in the ureter submucosa and muscularis. For the first time, two morphologically different types of MGCs were recognized: the moderate to electron-dense type I contained two types of 8-12 nuclei and cytoplasm poor in cell organelles which appeared non-functional. Type 1 MGCs were considered to be "old" and non-active cells. The electron-lucent to moderately dense type II MGCs contained 3-4 nuclei of one type, and cytoplasm rich in cell organelles. According to the performance of their organelles, type II MGCs were considered to be "young" and highly active cells. The human type II MGCs did not form the cytoplasmic membranous labyrinths previously described for the free moving MGCs obtained from experimental mice, and were suggested to be involved in the cell motility. As in murine MGCs, type II cells were incorporated in exocytic and endocytic activities aimed the degradation of the inner soft layer of the egg-shell. This study shows that individual macrophages were responsible for eliminating the outer and possibly the middle hard layers of the egg-shell.

A 20-year-old woman presented with abdominal pain of 4-h duration and of sudden onset. A plain abdominal radiograph showed a giant ureteral stone measuring 12 cm causing ureteral obstruction. Abdominal ultrasound revealed severe dilatation of the two upper thirds of the left ureter and a hydronephrotic ipsilateral kidney. Subsequent renal scan demonstrated that it was a non-functional kidney while the contralateral kidney was normal. A left nephroureterectomy was performed.

Inverted papilloma of the ureter is a rare lesion. We report a case of ureteral inverted papilloma with a non-functional kidney. A 66-year-old male was admitted to our hospital for investigation of left hydronephrosis. Left ureter tumor was diagnosed on X-ray (retrograde pyelogram, CT) and total nephro-ureterectomy was performed. The pathological diagnosis was ureteral inverted papilloma. Diagnosis and treatment of ureteral inverted papilloma are discussed.

We present the case of an 8-month-old boy with ureter triplication on the left side with non-functional upper pole due to ectopic ureterocele and a refluxive third ureter bud. We performed an upper pole heminephroureterectomy with resection of the ureterocele and of the refluxive third ureter bud and reimplantation of the lower pole ureter using the psoas hitch technique.
