    A clinical case of robot-assisted pyeloplasty with buccal mucosa graft of an extended recurrent stricture of the left ureteropelvic junction is presented. The patient had previously undergone left-sided laparoscopic antevasal pyeloplasty and retrograde endopyelotomies with ureteral stenting. However, after these interventions, the dilatation of the left pelvicalyceal system persisted, the patient complained of lumbar pain and periodic exacerbations of chronic pyelonephritis. Transperitoneal robotic access isolated the ureteral upper third and the ureteropelvic junction from scar tissue, after dissecting the narrowed ureteral section, its length was about 3.0 cm. In this regard, plastic surgery was performed with a buccal mucosa graft, the ureter was drained with a stent. There were no postoperative complications, and on day 3 the patient was discharged. The stent was removed 4 weeks after. During the control ultrasound examination, the renal pelvicalyceal system was relatively reduced, and the patient did not notice any pain

    Background. Urinary fistulas (UFs) are one of the most significant complications after partial nephrectomy. Placement of an ureteral stent eliminates urine extravasation in the majority of patients. However, some of them have persistent UFs despite upper urinary tract drainage. Such cases require retrograde injection of fibrin glue into the renal cavity through a ureteroscope or via the percutaneous approach. Some authors reported cases of simultaneous use of 2 stents and percutaneous cryoablation of the fistula, but these techniques are rare and, therefore, it is problematic to evaluate their efficacy.Objective: to evaluate the results of the new treatment method for the elimination of persistent UFs using the retrograde endoscopic percutaneous approach.Materials and methods. This study included 5 patients (3 males and 3 females) with UFs developed after kidney resection. Mean age of the patients was 55.8 years. The tumor size was 2.5 to 4.8 cm; mean R.E.N.A.L. score was 7.8. All patients had earlier undergone minimally invasive partial nephrectomy; the time between surgery and UF development varied between 3 and 10 days. Four out of 5 patients had a large amount of discharge from their paranephral drainage system, examination of which confirmed high creatinine level. Patients underwent flexible ureteropyelography in the lithotomy position. During this procedure, we identified the damaged calyx and then performed percutaneous puncture targeting the distal end of the endoscope at this calyx, ensuring that the tip of the needle appeared in the paranephral cavity in front of the injured calyx. Using the flexible ureteroscope, we inserted the needle into the pelvis, dilated the puncture opening along the string, and installed a nephrostomy drainage system (12 Fr). Then the endoscope was removed and the ureter was additionally drained with a stent. The stent was removed after 8-10 days with subsequent antegrade pyelography. If there was no extravasation, the nephrostomy tube was removed and the patient was discharged from hospital to continue treatment in outpatient settings.Results. All patients with UFs resulting from partial nephrectomy was successfully operated on. No complications were registered. The mean surgery time was 45.0 Β± 20.5 min (range: 40-65 min). Only two patients had some discharge from the fistula within 1 day after nephrostomy tube removal and it stopped without any additional interventions. Three patients had their fistula healed immediately. The treatment efficacy during the whole follow-up period of 18 Β± 4 months (range: 6-26 months) was 100 %.Conclusion. Ureteral stenting ensures elimination of UFs in the majority of patients after partial nephrectomy. In individuals with persistent UFs, retrograde endoscopic percutaneous drainage of the pelvicalyceal system is the method of choice, because it allows rapid and effective treatment of UFs.Π’Π²Π΅Π΄Π΅Π½ΠΈΠ΅.

    Endoscopic laser resection of a ureteral tumour in primary multiple malignant neoplasms

    No full text
    A case of the ureteral tumour endoscopic treatment is presented in a patient with primary multiple malignancies. In the case of polyneoplasia, there are usually two or more neoplasms of different localizations, including the organs of the urinary system. The kidney and prostate tumours are diagnosed more often, but in rare cases, ureter neoplasms. It is especially important to perform organ-sparing surgeries when diagnosing ureter neoplasms. In addition, chronic kidney disease after radical nephroureterectomy can be a relative contraindication to further chemoradiation therapy in polyneoplasias. In this patient, along with the breast and vulva neoplasms, a solitary tumour of the right ureter's lower third was detected, which was successfully removed endoscopically. The chosen method of minimally invasive treatment allowed to preserve a normal functioning kidney, to avoid the development of chronic kidney disease in the patient, who was later scheduled for chemotherapy
