It is important and of heavy workload for the client in C/S system to update.According to the actuality of our hospital,this paper suggests three methods and discusses the suitable conditions respectively.These methods have great value in practice.

ObjectiveTo study the clinical features of primary renal lymphoma.MethodsThe clinical,radiological features,treatment and prognosis of 3 cases of primary renal lymphoma are presented and discussed.ResultsSurgical intervention was carried out in 2 cases,and radiotherapy and chemotherapy were undertaken postoperatively.The other case was treated with chemotherapy alone.One patients survived more than 2 years and 2 more than 1 year.ConclusionsRadiological features are similar to those of renal cell carcinoma. Those with a preoperative diagnosis of primary renal lymphoma should be treated with chemotherapy with or without radiotherapy depending on the histological status,stage and volume of the tumor.

[Objective] To explore the clinical application of cutaneous ureterostomy-flap embedding in radical cystectomy plus urinary diversion. [Methods] The clinical data of 10 patients with bladder cancer treated with this method in our hospital during Feb.and May 2023 were involved.Cutaneous ureterostomy-flap embedding was used in urinary diversion.The stoma-free rate and stenosis rate of stomas within 1 year postoperatively, differences in renal function indicators 1 day before operation and 1 year after operation, urinary diversion-related complications within 6 months postoperatively, including hydronephrosis, urinary tract infections, renal stones were analyzed. [Results] All surgeries were successfully completed.At 1 year postoperatively, renal function indicators showed no significant difference compared to preoperative levels (P>0.05). At 6 months postoperatively, 1 patient developed renal stones, successfully treated with surgery; 2 had urinary tract infection, recovered after antibiotic treatment; 2 had mild unilateral hydronephrosis, alleviated with conservative management.At 1 year postoperatively, the catheter-free rate was 80%(8/10), with no worsening of hydronephrosis or occurrence of ureteral obstruction, and the stent placement duration ranged from 97 to 211 days, average (151.63±42.47) days.The ureteral stent was not removed in 2 patients within 1 year, so the stoma stenosis rate was 20%(2/10). [Conclusion] The application of flap embedding in urinary diversion following radical cystectomy is a simple and safe procedure, with few postoperative complications, high success rate of stent removal, and overall favorable outcomes.
