Large Hepatic Subcapsular Hematoma Secondary to Double-J Stent Placement

A 39-Year-Old Woman with Endometriosis Who Developed a Subcapsular Liver Hematoma Following Laparotomic Surgical Left Adnexectomy, Rectosigmoid Anastomosis, and Bilateral Ureteral Reimplantation

BACKGROUND Endometriosis is a chronic inflammatory disease caused by endometrial tissue that grows outside the uterus. Deep endometriosis surgery is associated with considerable rates of complications, although such rates are lower in surgical procedures carried out by expert surgical teams. This report details a case of a rare but life-threatening complication in the postoperative period following 72 h of endometriosis surgery: a giant subcapsular hepatic hematoma, which was successfully managed conservatively. CASE REPORT Here we describe the case of a 39-year-old woman with deep endometriosis with ureteral, ovarian, and intestinal involvement requiring multidisciplinary surgery. She presented with severe anemia, respiratory distress, and oliguria 72 h postoperatively. A 3-phase computed tomography (CT) scan revealed a giant intrahepatic subcapsular hematoma (180×165×50 mm) lateral to the right hepatic lobe, which was managed conservatively. The patient evolved favorably and the hematoma was reduced (77×16 mm) in a follow-up CT scan performed 5 months later. CONCLUSIONS Giant liver hematoma is a rare, life-threatening complication. The current experience relating to its management remains largely limited owing to the rarity of the condition and paucity of published cases. Actually, we found no articles on hepatic hematoma in the context of endometriosis surgery. Early diagnosis and treatment are essential to reduce the patient's risk of death. Imaging diagnosis plays an essential role.

Perinephric Hematoma Associated with Pyelonephritis Following Ureteral Stent Placement for Ureteral Obstruction Causing Hydronephrosis

BACKGROUND Perinephric hematomas are rare, especially following ureteral stent placement. Etiologies of perinephric hematomas include post-extracorporeal shockwave lithotripsy, Wunderlich syndrome, and renal cell carcinoma, none of which occurred in our patient, who underwent stent replacement. Subcapsular renal hematoma, rather than a perinephric hematoma, can occur following double-J ureteral stent placement. Also, renal parenchymal perforation leading to perinephric hematoma development are complications of double-J ureteral stent placement. Herein, we present a case of a perinephric hematoma following a double-J ureteral stent placement for a ureteral obstruction causing hydronephrosis. CASE REPORT A 43-year-old woman with type 2 diabetes mellitus, hypertension, systemic lupus erythematosus, and recurrent nephrolithiasis presented to our hospital with left flank pain of a 1-day duration. The patient was found to have an obstructive kidney stone causing hydronephrosis. She underwent stent placement and then developed a perinephric hematoma days later. Typically, hematomas are treated conservatively and have spontaneous resolution. The patient received 2 weeks of intravenous antibiotics and 2 more weeks of oral antibiotics, and failed conservative treatment. She re-presented to our hospital 3 days after discharge. Upon the second admission, a perinephric drain was placed. The patient was given another course of antibiotics and was discharged 18 days later. CONCLUSIONS A perinephric hematoma is a rare complication after ureteral stent placement. Perinephric hematoma development can be decreased by controlling blood pressure, treating preoperative urinary tract infections, and shortening operating time during ureteroscopy. It is important to reevaluate potential causes of continued abdominal pain with laboratory testing and repeat imaging.
