Surgery for renal cell carcinoma in two European urologic clinics: to compare or compete?

OBJECTIVES: To evaluate and compare the incidence, TNM staging and the current strate- gy for the surgical treatment of renal cell carcinoma (RCC) in two European urologic institutions, situated in Varna, Bulgaria and in Bari, Italy. Both clinics have sound experience of RCC surgery, and modern laparoscopic equipment. A retrospective chart review of all patients with RCC diagnosed and treated in the last year was conducted at the two sites. MATERIALS AND METHODS: In total, 88 patients (66 males and 22 females, mean age 58 years, range 24-81 years) were enrolled in the study. Comparisons were made between some clinical and pathologic parameters with an established prognostic and therapeutic impact. The type of surgery perormed at both sites was analyzed as well. All these comparative studies were performed in relation to the 2008 EAU guidelines on the current management of RCC. Commercially available statistical software was used for the purpose. RESULTS: The results showed no difference between the two sites regarding the RCC incidence and the patients' age and gender. Significant differences (p value < 0.0001) emerged in terms of: the median size of the tumors at surgery (8.5 cm in Varna, SD + 4.04 vs. 4.4 cm in Bari, SD _ 2.02); T-stage of the tumor (Varna T T2-30%, T3-22%, T4-15% vs. Bari T1-64%, T2-12%, T3-24%, T4-0%); N-positive disese (24% vs. 2%); distant metastases (20% vs. 2%) and presence of necrosis in the renal masses (37% vs. 19%). Thus, 85% of Varna patients underwent open radical nephrectomy, 11% nephron-sparing surgery and 4% explorative laparotomy, due to inoperability of the renal mass. Only 29% of Bari patients were treated by open radical nephrectomy, 12% underwent laparoscopic nephrectomy, 57% open partial nephrectomy and 2% laparoscopic partial tumor resection. CONCLUSIONS: These numbers demonstrate more advantageous tumour features at the Italian clinic in terms of organ-sparing surgical options (open and laparoscopic), whereas in the Bulgarian clinic the tumour features pose certain limitations to the application of modern surgical techniques. This difference is due to early diagnosis of RCC in Italy, allowing treatment of smaller volume tumors.

Ileal substitution of a radiologically injured duplex female ureter via novel antireflux technique.

A 34-year-old female patient underwent total hysterectomy and pelvic irradiation for uterine malignancy, which led to iatrogenic fibrotic injury of the distal ureter. Reconstructive surgery was performed, and the ureter was replaced by an isolated ileal segment. Ureteroileal anastomosis was created using the antireflux serous-lined extramural tunnel technique, while the distal end of the isolated ileal segment was widely anastomosed with the bladder. Within a 1-year follow-up, excellent results were achieved, with complete recovery of the patient's renal function and previous quality of life. This technique could be a viable option when large ureteral defects are encountered.
