ABSTRACT
Ureteral calculi after lingual mucosal ureteral reconstruction are rare. In this paper, we reported a case of a male patient who had undergone robotic-assisted laparoscopic lingual mucosal right ureteroplasty. Calculi were found in the right reconstructed ureteral segment 4 months after surgery. Then the patient underwent transurethral ureteroscopic holmium laser lithotripsy combined with a stone retrieval basket, and postoperative urological CT showed no residual calculi in the right ureter. No recurrence of right ureteral calculi or complications were observed during 20 months of follow-up.
ABSTRACT
【Objective】 To analyze the risk factors of ileus after radical cystectomy, and to construct a nomogram predictive model accordingly. 【Methods】 Clinical data of patients who underwent radical cystectomy during Jan.2018 and Dec.2021 were collected. The risk factors related to postoperative ileus were assessed with Logistic univariate and multivariate regression analysis. After that, the predictive model was constructed and its specificity and accuracy were verified. 【Results】 A total of 326 patients were included, 65 of whom developed ileus. Statistical analysis showed that gender, lymph node dissection, serum creatinine and albumin were correlated with postoperative ileus. The area under the receiver operating characteristic curve of the model was 0.769 (95%CI:0.724-0.802). Bootstrap correction curve showed that the model had good prediction accuracy. 【Conclusion】 Male, lymph node dissection, elevated postoperative serum creatinine and postoperative blood albumin decrease are predictors of ileus. The nomogram predictive model based on these predictors can predict the probability of ileus after radical cystectomy.
