ABSTRACT
Localized ureteral amyloidosis is a rare disease clinically and radiographically similar to ureteral carcinoma. We reported a 56-year-old man with painless gross hematuria. CT and Magnetic resonance urography (MRU) examinations showed tumor signs and ureteral amyloidosis was diagnosed by ureteral biopsy. Laparoscopic partial ureterectomy combined with boari flap was performed and the patient's renal function was preserved. There was no local recurrence and distant metastasis during the 1-year follow-up.
ABSTRACT
Objective: To report a case of distal ureterectomy with robotic-assisted laparoscopic reimplantation using a Boari flap technique. Material and Methods: We report a 55 year old man with a diagnosis of distal ureteral urothelial carcinoma without multifocality. Results: A radical distal ureterectomy and robotic-assisted laparoscopic vesicoureteral reimplantation using a Boari flap technique was performed with the da Vinci S-HD surgical system. The operative time was 210 minutes, the estimated blood loss was 200 mL. The hospital stay was 48 hours, without perioperative complications. The histopathological study showed a high grade non-muscle invasive urothelial carcinoma of the distal ureter (pT1NxMx) with negative margins. Conclusions: The distal radical ureterectomy with Boari replacement is feasible and more precise with robotic assistance. Its oncological role must be demostrated with a larger number of cases.
Objetivo: Comunicar un caso de tumor ureteral distal tratado con ureterectomía radical y neoimplante vesicoureteral con técnica de Flap Boari asistida por robot. Material y Métodos: Paciente hombre de 55 años, con diagnóstico de carcinoma urotelial de uréter distal sin compromiso multifocal. Resultados: Se realizó ureterectomía distal radical y neoimplante vesicoureteral con Flap Boari asistido por Robot da Vinci S-HD. El tiempo operatorio fue de 210 minutos, con un sangrado estimado de 200 ml. La estadía hospitalaria fue de 48 horas, sin complicaciones perioperatorias. El estudio histológico mostró un carcinoma urotelial de alto grado con infiltración de la lámina propia (pT1NxMx) y márgenes quirúrgicos negativos. Conclusiones: La ureterectomía radical distal con reconstrucción tipo Boari es técnicamente factible y más precisa con la asistencia robótica. Su rol oncológico requiere de validación con mayor número de casos.

We report 2 cases of unusual ureteral tumor. A case appeared as bladder tumor causing ureteral obstruction by outgrowing of the tumor of terminal ureter into the bladder wall. The surface of bladder mucosa was intact. The other one presented as a large retroperitoneal mass causing obstruction of the external iliac vein such as an ovarian tumor. The literature is reviewed briefly.

A clinical observation was made on 14 cases of transitional cell carcinoma of the renal pelvis and ureter whose diagnosis was confirmed pathologically at Kyung Hee University Hospital during the period tom November, 1971 to June, 1984. The results were as follows 1. The age of patient at the time of the diagnosis ranged from 42 to 75 years (mean 57.9 years), with highest incidence during the 6th decade. 11 tumors occurred in male patients and 3 in female patients, for a ratio of 3.7 : 1. 2. Common presenting symptoms were gross hematuria (92.8 %) and pain (28.5 %). 3. IVP was performed in all patients. A filling defect in the renal pelvis or ureter was found in 6 cases, and non-visualized kidney in 6 cases. RGP was performed in 9 patients and was useful to demonstrate a filling defect. 4. Urine cytology was positive in 6 of 13 patients. 5. Nephroureterectomy including a cuff of bladder was performed in 13 patients and simple nephrectomy was done in 1 patient who was misdiagnosed as hydronephrosis due to UPJ obstruction. 6. The tumors were staged into 4 Stages postoperatively. 5 patients had Stage A tumors, 2 Stage B, 5 Stage C and 2 Stage D. 1 patient had Grade I tumor, 6 Grade II, 4 Grade III and 3 Grade IV. In 3 patients, there were synchronous tumors in renal pelvis and ureter. Three patients subsequently developed bladder tumor. 7. 7 patients were died in 3 to 18 months (average 7.8 months) after initial treatment and all were categorized into Stage C and D.

Primary ureteral tumor accounts for an estimated about 1 percent of all tumors of the urinary tracts. We observed one case of the ureteral tumor in 65 years old male patient and he was treated by complete nephroureterectomy with an excision of a cuff bladder wall around ureteral orifice. A case of primary ureteral tumor was reported with a brief review of the literatures.

Records of 15 patients of primary ureteral tumor which were managed in Seoul National University Hospital during 13.5 years period from January 1971 to June 1983. 1. Primary ureteral tumor comprised of 2% of all urothelial tumors and the ratio of bladder:pelvis:ureter was 40:2:1. 2. There were 11men and 4 women (ratio of 3:1) with a mean age of 62.7 years. 3. The most frequent site of ureteral tumor was the lower one third of the ureter (53%). 4. Most frequent presentation was gross hematuria. usually intermittent and painless (100%). 5. Non-visualization of the kidney was the most prevalent finding (73%) on excretory urogram. Retrograde pyelogram was necessary in 11 patients whose findings of IVP was insufficient for diagnosis, and these procedures provided definite diagnosis in 9 of 11 patients. 6. Urine cytology was positive in 4 of 13 patients. 7. Cystoscopy was performed in all patients and which revealed concomitant bladder tumor in3 patients and tumor in ureteral orifice in 2 patients. 8. There was close correlation between the grade of cellular anaplasia and the degree of invasion. 9. There were 3 recurrences (50%) in the ureteral stump in 6 patients treated by nephrectomy and partial ureterectomy.

Tumor of the ureter is malignant and rare, but recently the incidence rate was progressively increased due to developed methods of diagnostic procedures. Here, we report two cases of ureteral cancer combined with urinary stones in the department of urology, Seoul Red Cross Hospital, with some literatures.
