Abstract:Objective To explore the application of retrograde placement of double J stent through urinary catheter in totally laparoscopic radical cystectomy and orthotopic ileal neobladder.Methods Retrospectively analyzed the data of 5 patients who underwent retrograde placement of double J stent through urinary catheter in totally laparoscopic radical cystectomy and orthotopic ileal neobladder from September 2020 to October 2021.Results All the 5 patients underwent retrograde placement of double J stent through urinary catheter in totally laparoscopic radical cystectomy and orthotopic ileal neobladder, and no major complications occurred. Double J stent was placed in the neobladder with the above method, operative time was 2 ~ 4 min, with an average of (2.8 ± 0.6) min, and the average hospital stay was (13.0 ± 0.8) d. At present, the recovery of urination in 5 patients was good, and no urinary leakage and infection occurred during the recovery process.Conclusion Retrograde placement of double J stent has been successfully used in orthotopic ileal neobladder with totally laparoscopic radical cystectomy. It can shorten the operation time without destroying pneumoperitoneum, and is conducive to the recovery of urinary function of patients after operation. It is a safe, effective and convenient auxiliary method in neobladder operation.
