Clinical analysis of retroperitoneoscopic nephroureterectomy for renal tuberculosis

To explore the feasibility and safety of retroperitoneoscopic nephroureterectomy for kidney tuberculosis.

Forty-eight retroperitoneoscopic nephroureterectomies and thirty-five nephroureterectomies for kidney tuberculosis procedures were performed from June 2008 to December 2014. The patients consisted of 53 males and 30 females with a mean age of 36 years (range: 26-51 years). The patients' data were reviewed and analyzed.

The retroperitoneoscopic nephroureterectomy procedures were completed successfully in 48 cases with no conversions to open surgery. The mean operating time was 170 minutes (range: 121-258 minutes), the mean blood loss was 110 ml (range: 70-250 ml), and the mean hospital stay was 5.70 days (range: 5-14 days); these were all much less than nephroureterectomy procedures (P < 0.05). A total of five minor complications (10.4%) occurred, injury to the peritoneum was observed in three patients, and infection at the incision site was observed in two patients, there were no obvious difference between the two surgical methods (P > 0.05). Seventy-five patients were followed up, and the average follow-up time was 12.5 months (range: 6-20 months). All the patients recovered without any lesions remaining.

The results of this study indicate that retroperitoneoscopic nephroureterectomy is a feasible, safe, effective, and less invasive treatment modality for treating renal tuberculosis.
