Background
Ureteral double- J stent is usually inserted by retrograde approach to treating obstructed upper urinary tract. The antegrade approach, can be suitable alternative in certain situations without general or spinal anesthesia. The present study demonstrates the indications, success rate, and complications of this approach in treatmenting malignant obstructive uropathy.
Methods
Data of consecutive patients with malignant obstructive uropathy who underwent antegrade ureteral stenting in the Department of Interventional Radiology at Sahloul hospital from January 2013 to February 2020 was retrieved and retrospectively analyzed.
Result
A total of 188 attempts of antegrade ureteral stent insertion was performed during the study period (left side = 78, right side = 82, bilateral = 14). The mean age was 54 years (range: 9–91 years). The indication of the antegrade stenting was the failure of retrograde approach in 63 patients.The single-stage approach was performed 103 times. A percutaneous nephrostomy was placed for the average duration of 22.4 days (range: 2–60 days) for subsequent attempts. Only four patients required general anesthesia. Ureteral obstruction was caused by bladder cancer (n = 92), uterine cancer (n = 31), prostate cancer (n = 28), colorectal cancer (n = 15) and retroperitoneal tumor (n = 8). A protective nephrostomy was left in situ in 44 cases for 48 h. Clinical success was achieved in 96% of the cases. Two and three patients required hospitalization for perirenal abscess and hematuria, respectively.
Conclusion
This retrospective study shows that antegrade ureteral stent insertion has a high success rate with minimal complications.

Background
chronic lymphocytic leukemia (CLL) patients have a high risk of occurrence of secondary cancers. This risk is three times higher for all cancers and eight times higher for skin cancer. The coexistence of CLL and adenocarcinoma of the prostate is rare.
Case presentation
We report a case of a66-year-old man who underwent radical prostatectomy for prostate carcinoma. The final histopathological diagnosis of Gleason 7 adenocarcinoma of the prostate with incidental Rai stage I chronic lymphocytic leukemia (CLL) was made. No further investigations or treatment was offered due to the age and low disease stage. At the last follow-up of 12 months, the patient is alive, without disease progression for both lymphoma and prostate, with a PSA value of 0.03 ng/ml.
Conclusion
Early detection of lymphoma after radical prostatectomy will allow optimal management. The analysis of this link requires, therefore, additional investigations.
