Introduction: Spontaneous rupture of kidney may involve collecting system or parenchyma. Parenchymal rupture usually occurs in patients with renal cell carcinoma, angiomyolipoma, renal cysts, arteriovenous malformation or vascular diseases such as periarteritis nodosa. Collecting system rupture is usually a rare complication of obstructive urolithiasis. We describe the unusual cases of spontaneous kidney rupture in patients with acute urinary obstruction. Case presentation: The case report describes the left parenchymal kidney explosion related to ipsilateral ureteral obstruction caused by a single ureteral stone. The patient reached our emergency department with acute left flank pain and massive haematuria. At the moment of admission, the patient was in stage III hypovolemic shock and had a lower haematocrit (haemoglobin = 4.9 g/dL). Despite blood transfusions, emergency surgical exploration, extrafascial nephrectomy and intensive support care, the patient died twelve hours after surgery. Conclusions: Parenchymal renal rupture can be a life-threatening emergency. Despite its rarity, in the differential diagnosis of acute abdomen, parenchymal renal rupture should always be considered in patients with abdominal pain and an anamnesis or history of urinary stones, pointing out the need of early diagnosis also in benign urological conditions.

Introduction: The aim of this study was to evaluate the role of TAP block in improvement of anesthesiological management and perioperative surgical outcomes of robot-assisted laparoscopic radical prostatectomy (RALP). Methods: We consecutive enrolled 93 patients with prostate cancer whose underwent RALP at our department from January 2019 to December 2019. Group A included 45 patients who received bilateral TAP block, and Group B included 48 patients who did not received TAP block. TAP blocks were always performed by a single anesthesia team. An elastomeric pump device was used in all patients for post-operative pain management. TAP block was performed according to Rafi’s technique, with Ropivacaine 0.375% and dexamethasone 4 mg. Mean values with standard deviations (±SD) were computed and reported for all items. Statistical significance was achieved if p-value was ⩽0.05 (two-sides). Results: The two groups showed no difference in the most important demographics and baseline characteristics ( p > 0.05). Group A showed a significant longer time of anaesthesia. Moreover, Ketorolac doses (started dose plus continuous post-operative infusion via elastomeric pump) used in Group A were significantly lower than Group B. Despite this, Group B showed statistical significant higher value of NRS PACU and at 12, 24, 48, 72 h than Group A but not at 96 h. Rescue analgesic medication use was significantly higher in the Group B than Group A. Moreover, patency of the intestinal tract and time to ambulation was significantly lower in the Group A. Discussion: The use of TAP block during a RALP is a safe procedure that can be applied more appropriately to achieve better pain control. A multimodal protocol that includes locoregional anesthesia, reduction of intra and postoperative use of strong opiates, correct placing of the patient and the use of low pneumoperitoneum pressures should be implemented in order to reach a faster and better post-operative full recovery of patients whose underwent RALP.
