Introduction:
Surgical exploration in complete ureteropelvic-junction disruption (CUPJD) is still recommended by many authors. Conservative approach to pediatric renal trauma (RT) includes minimally invasive techniques such as nephrostomy, angioembolization or double-J stent placement.
Case Report:
A 14-year-old patient with CUPJD was treated conservatively. CT-scan revealed active bleeding of the renal artery and significant urine extravasation. Coil angioembolization and nephrostomy placement were performed. An attempt to place a double-J stent was unsuccessful and surgical reconstruction was scheduled. Before surgery, methylene-blue was injected through the nephrostomy observing blue urine output through urethra. Antegrade pyelogram revealed drainage from the urinoma to the ureter. A new attempt to place an internal-external double-J-stent was successful. After 5 weeks, it was removed with total restoration of the urinary tract.
Conclusion:
Complete urinary tract restoration in some cases of CUPJD following RT is possible through a nonoperative approach. It can be safe and effective, reducing the risk of complications associated with complex surgeries.

01:24Ostomy Care
An ostomy is a surgical procedure that creates an artificial opening from the intestines to the outside of the body, allowing for the rerouting of effluent. This opening is known as a stoma. A stoma usually protrudes above the skin surface, appearing pink or red, moist, and round, and it lacks nerve sensations.
There are different types of ostomies, including colostomies, ileostomies, and urostomies:
