Objective: To evaluate the treatment modalities of total ureteral avulsion and to clarify the risk factors of this serious complication. Methods: This study retrospectively analyzed the data of 3 patients with complete ureteral avulsion during ureteroscopy. Of the three patients, two had distal ureteral complete avulsion, and one total ureteral avulsion on both ends. Ureteroneocystostomy (UNC) was immediately performed after distal ureteral avulsion cases. Ileal ureter substition was performed on the same session after the total ureteral avulsion in both ends. Two of the patients were under chronic use of corticosteroid treatment due to diagnosis of idiopathic trombocytopenic purpura and myastenia gravis and all patients had unsuccesful shockwave litotripsy (SWL) treatment history with at least 1 month period before surgery. Results: The patient who had ileal ureter substitution was followed at 3-month intervals by ultrasonography and renal function tests and she was uneventful after a 2 year follow-up period. The patients treated with UNC were followed up at 3 month interval by ultrasonography and renal function tests. They had normal renal function 1 year after the operation Conclusion: Complete ureteral avulsion is a rare but severe complication. Treatment modality can vary and ileal ureter can be applied succesfully in the total ureter avulsion in both ends when bladder capacity is not enough for a Boari flap. Failed SWL and/or corticosteroid treatment history of patients seems to increase the risk of the ureteral avulsion.KEY WORDS: Avulsion; Lithotripsy; Ureterorenoscopy. quency of complications varies between 0.5% and 10% in the literature (1-3). Ureteral avulsion is the most serious complication and occurs in 0-0.5% patients (4). Treating ureteral avulsion is a challenge. Patient comorbidities, the condition of the kidney, severity of the ureteral damage, and experience of the surgeon can affect the choice of treatment. In this study, we aimed to discuss our experience and possible leading factors of this serious complication in the light of the current literature. MATERIALS AND METHODSWe retrospectively analyzed three ureteral avulsion cases and treatment modalities at two referral hospitals between January 2008 and October 2014. All patients underwent rigid ureteroscopic procedures for removing ureteral stones, and ureteral avulsion occurred during the retrograde examination of the ureter. Of the three patients (1 man, 2 women; age: 28-65 years, one right, two left), the avulsed ureter was repaired during the same session of the ureterorenoscopic surgery. The ureter stones were located in the distal ureter in two patients and in the proximal ureter in one patient. All patients had unsuccessful SWL treatment and at least a 2 week interval before further investigation and treatment were applied. Two patients who have been diagnosed with idiopathic thrombocytopenic purpura and myastenia gravis received chronic corticosteroid treatment. The patients were evaluated with abdominal X-ray, ultrasonography, int...

Choriocarcinoma is the most malignant tumor of gestational trophoblastic neoplasia. It grows rapidly and metastasizes to the lung, liver, and less frequently, the brain. Metastases to the kidney are rare in the literature, and bilateral involvement is even more scarce. Renal involvement of choriocarcinoma is highly exceptional and may mimic renal cell carcinoma. Here we report a case of bilateral renal choriocarcinoma presenting 5 years after a history of a total anterior hysterectomy because of a hydatidiform mole.

Patients with previous operations, comorbidities, and high ASA score are at risk of neuromuscular complications during RALP. Lower BMI and having an implant also lead to higher postoperative pain. Operating room staff and anaesthesia team should be very careful with patients undergoing RALP in steep Trendelenburg and low-lithotomy position.

Introduction: The aim of this study was to compare the safety of ultrasonography-guided (UG) puncture and fluoroscopy-guided (FG) upper pole access (UPA) in percutaneous nephrolithotomy (PCNL). Methods: Consecutive patients with a solitary UPA were enrolled into the study from 2012 to 2020 and analyzed in a retrospective manner. In total, 177 patients were divided into 2 groups according to the method during the puncture phase of the access: FG (n = 105) and UG (n = 72). The UG and FG groups were compared in terms of complications (i.e., pleural injury and blood transfusion rate) and surgical outcomes. Results: Gender, side, grade of hydronephrosis, type of access (i.e., supracostal vs. subcostal), Guy's stone score, age, stone diameter, skin-to-stone distance, and stone density were similar in the 2 groups (p > 0.05). Only in 25.9% of cases, UPA was done using a subcostal approach. The overall complication rates were similar between the groups (p > 0.178). For the UG and FG groups, the rate of pleural injury (8.5 vs. 4.1%) and the blood transfusion rate (8.5 vs. 2.8%) were also similar (p > 0.05). The fluoroscopy time and mean hemoglobin drop were significantly lower in the UG group than in the FG group (134.2 vs. 82.2 s, respectively, p = 0.001; 20.8 ± 9.8 vs. 16.8 ± 7.9 g/L, respectively, p = 0.001). Stone-free rate (SFR) was also similar in the FG and UG groups (77.1 vs. 75.0%, respectively, p = 0.742). Conclusion: While it is commonly expected that the complication rates are lower in UG puncture for UPA in PCNL than they are in FG puncture, the present study failed to show this difference. However, the radiation exposure time seemed to be lower in UG puncture than FG puncture and had a similar stone-free rate (SFR) for UPA in PCNL.
