Abstract:
Objective To evaluate the feasibility of fluoroscopy-guided anterograde forceps biopsy for diagnosing uretero-ileal neobladder anastomotic stenosis.Methods Twenty-two patients who underwent Bricker surgery presented with hydronephrosis were selected.Using a catheter-wire technique,percutaneous nephrostomy tract was used to access the uretero-ileal neobladder stric-ture and establish a sheath biopsy channel.Forceps biopsy was performed at the uretero-ileal neobladder anastomotic site,followed by placement of a 10.2F ureteral stent.The technical success rate,complications,biopsy sensitivity,specificity,accuracy were recorded,and preoperative versus postoperative white blood cell counts,creatinine,and urea nitrogen levels were compared.Results The tech-nical success rate was 100%(22/22),with no serious complications,such as ureteral perforation and major bleeding.The accuracy,sensitivity and specificity of the biopsy were 95.45%(21/22),85.71%(6/7)and 100%(15/15),respectively.Preoperative and post-operative white blood cell counts were(9.17±2.16)× 1012/L vs(6.03±1.51)×1012/L,creatinine levels were(219.95±78.47)U/mL vs(78.91±17.23)U/mL,and urea nitrogen levels were(19.85±5.27)U/mL vs(5.95±1.60)U/mL.All three parameters showed statistically significant differences(P<0.05).Conclusion The fluoroscopy-guided anterograde forceps biopsy for diagnosing uretero-ileal neobladder anastomotic stenosis is safe and feasible.
