Abstract:
Objective To evaluate the application of percutaneous nephroscopy in the treatment of upper urinary tract transitional cell carcinoma, particularly renal pelvic carcinoma. Methods From June 2006 to June 2010, eight cases (with 10 sides) of renal pelvic carcinoma received percutaneous nephroscopy tumor resection. There were six males (with 7 sides) and two females (with 3 sides) in the study group. There were six cases with solitary kidney and two cases with bilateral renal pelvic tumors. There were four cases with high-grade tumors and six cases with low-grade tumors. The age of patients ranged from 52 to 72 yrs (average 61.2 yrs). Tumor sizes ranged from 0.5 to 3.5 cm (average 2.6 cm). Patients were treated with laser or electrocautery through percutaneous nephroscopy. A ureteral stent was placed in the patients after the procedure. Chemotherapy was administered postoperatively through the nephrostomy tube. Results All the operations were successfully completed uneventfully. The operative time was 45-95 min (average 73 min), estimated blood loss was 20-300 ml (average 50 ml). No remarkable differences were found in serum creatinine levels before and after operation. After 10 to 36 mon. follow-up by CT, MRI, and ureteroscopy, one patient died of tumor metastasis and two patients had local tumor recurrence. The remaining patients had no local recurrence. Conclusions Percutaneous nephroscopy in treating renal pelvic tumor is safe and feasible. This is a better choice for the renal pelvic carcinoma patients who are unsuitable for ureteronephrectomy.
