Abstract Objectives To compare surgical and functional outcomes between off‐clamp robot‐assisted partial nephrectomy with indocyanine‐green tumour marking through preliminary superselective embolization and on‐clamp robot‐assisted partial nephrectomy with intraoperative ultrasound identification of the renal mass. Material and methods One hundred and forty patients with a single renal mass underwent indocyanine‐green fluorescence‐guided off‐clamp robot‐assisted partial nephrectomy with preoperative superselective embolization (Group A, 70 patients) versus intraoperative ultrasound‐guided on‐clamp robot‐assisted partial nephrectomy without embolization (Group B, 70 patients). We assessed operative time, intraoperative blood loss, complications, length of stay, renal function, need for ancillary procedures and blood transfusions. Results Mean tumour size was 24 versus 25 mm in Group A versus Group B (p = 0.19). Mean operative time was 86.5 versus 121.8 min (p = 0.02), mean blood loss was 72.8 versus 214.2 mL (p = 0.02), and mean haemoglobin drop on postoperative day 1 was 1.1 versus 2.6 g/dL (p = 0.04) in Group A versus Group B. One‐month creatinine, hospital stay and enucleated tumour volume were comparable. Ten postoperative complications occurred in Group A (13.3%) and 11 in Group B (15.3%). Following superselective embolization, no patients required blood transfusions versus two patients in Group B. Postoperative selective renal embolization was needed in one case per group. Conclusions Preoperative superselective embolization of a renal mass with indocyanine‐green before off‐clamp robot‐assisted partial nephrectomy significantly reduces operative time and intraoperative blood loss compared to on‐clamp intraoperative ultrasound‐guided robot‐assisted partial nephrectomy. A longer follow‐up is needed to establish the effect on renal function.

ObjectivesPostoperative haematuria is a feared complication following prostate enucleation, and it may occur even weeks after discharge. We evaluated the risk of bleeding after discharge and its predictive factors in patients who underwent Thulium laser enucleation of the prostate (ThuLEP). MethodsBetween January 2015 and December 2018, patients with surgical indication for benign prostatic hyperplasia underwent ThuLEP in 4 urology departments. All procedures were performed by experienced urologists. Postoperative haematuria was defined as macroscopic haematuria occurring 7 days after discharge. Readmission rate due to macroscopic haematuria was assessed. Logistic regression models tested for predictors of postoperative bleeding requiring readmission. ResultsOverall, 748 patients were included, and 52 (6.9%) of them were readmitted after discharge because of macroscopic haematuria. No cases of deep venous thrombosis or pulmonary embolism were diagnosed. Mean length of stay for surgical treatment was 2.1 days, and mean hospitalization for readmission was 5.6 days. None of the readmitted patients required reintervention, while 46.1% of them required blood transfusions. Diabetes mellitus (P < 0.05), a long bridge of oral anticoagulant drugs with low molecular weight heparin (LMWH) (P < 0.05) and history of constipation (P < 0.05) were significant predictors of readmission after discharge due to macroscopic haematuria. ConclusionsPatients with a clinical history of diabetes mellitus or constipation and patients who undergo a long bridge of oral anticoagulant therapy with LMWH are at higher risk of bleeding requiring readmission after ThuLEP.
