Stone Passage

Introduction: Previous radiological studies revealed that stones lodge more frequently in the ureterovesical junction (UVJ) as well as the proximal ureter. Factors that prevent stone passage from the proximal ureter are not well studied. Aim: To explore the site of the lodged stones in the proximal ureter with direct observation during laparoscopic ureterolithotomy. Materials and methods: Between November 2014 and February 2015, we included 26 patients including 18 men and 8 women with stones larger than 10 millimeters in the proximal ureter who were candidate for laparoscopic ureterolithotomy. We prospectively recorded the site of the lodged stones in the ureter during laparoscopic ureterolithotomy in relation with the sites of ureteral stenosis as well as the gonadal vessels. Results: Among 26 patients with ureteral stone, in 19 cases stone was found close to the gonadal vein compared with seven cases that stone was in other locations of the ureter (p = 0.02). The characteristics of patients and stones were not different in cases that the stone was close to gonadal vessels compared with other locations. Conclusions: This study showed that most of the stones lodged in the proximal ureter were in close proximity with gonadal vessels. Gonadal vessels may be an extrinsic cause of ureteral narrowing.

Introduction and Objectives Ureteral stenosis and vesicocoureteral reflux after renal transplantation represent a key concern because of their incidence and the associated morbidity. Prompt diagnosis and minimally invasive treatment are mandatory in immunosuppressed patients with single kidney. The aim of this study is to evaluate the success rate of the endourological techniques in the management of such complications. Materials and Methods Between January 1996 and December 2006, 647 kidney transplants were performed. Urinary tract continuity was re-established by ureteroneocystostomy according to Gregoir-Lich technique. We observed 13 cases of ureteral stenosis (2%) and 11 cases of symptomatic vesicoureteric reflux (1.7%). The endourogical procedure was performed in 13 patients: 5 cases of II-III grade vesicoureteric reflux, 4 early ureteral stenosis and 4 late ureteral stenosis. Patients with vesicoureteric reflux underwent endoscopic injection of macroplastique in 4 cases and Durasphere in 1. Early ureteral stenoses were treated using balloon dilation in 2 cases, balloon dilation and laser endoureterotomy in 3, ureteral stent placement in the other. Recipients with late stenosis underwent laser incision and balloon dilation in 2 cases, balloon dilation in 1 and a laser incision only in the last case. Combined antegrade and retrograde endoscopic approach was performed in 7 patients, whereas retrograde access in 1. Results Endourologic treatment was successful in 9 cases (69.2%); 2 patients required open reconstructive surgery due to endourological technique failure (early ureteropelvic junction stricture, late ureterovesical anastomotic stricture). Vesicoureteric reflux was corrected in 3 patients (60%), 2 patients underwent uretero-ureterostomy for recurrent reflux. No technique-related morbidity was observed. With a mean follow-up of 81.6 months, 8 patients show normal renal function, 5 patients have returned to haemodialysis (4 for chronic rejection, 1 for carcinoma in the graft). Conclusions Considering their low morbidity and the satisfactory success rate, we claim that endourological procedures should be considered the preferred treatment for ureteral stenosis and vesicoureteric reflux in selected patients.

Rare Situation

Krukenberg tumors from pulmonary adenocarcinoma represent an extremely rare situation; only a few cases have been reported. The aim of this paper is to report an unusual such case in which almost complete dysphagia and ureteral stenosis occurred. The 62-year-old patient was initially investigated for dysphagia and weight loss. Computed tomography showed the presence of a thoracic mass compressing the esophagus in association with a few suspect pulmonary and peritoneal nodules, one of them invading the right ureter. A biopsy was performed laparoscopically on the peritoneal nodules. The right adnexa presented an atypical aspect; right adnexectomy was also found. The histopathological and immunohistochemical studies confirmed that the primitive origin was pulmonary adenocarcinoma. Although both peritoneal carcinomatosis and ovarian metastases from pulmonary adenocarcinoma represent a very uncommon situation, this pathology should not be excluded, especially in cases presenting suspect pulmonary lesions.

Introduction. Nowadays, minimally invasive surgery in kidney transplantation is a reality thanks to robotic assistance. In this paper, we describe our experience, how we developed the robotic assisted Kidney transplantation (RAKT) technique, and analyze our results. Material and Methods. This is a retrospective study of all RAKTs performed at our center between July 2015 and March 2020. We describe the donor selection, surgical technique, and analyze the surgical results and complications. A comparison between the first 20 cases and the following ones is performed. Results. During the aforementioned period, 82 living donor RAKTs were performed. The mean age was 47.4±13.4 and 50 (61%) were male. Mean body mass index was 25±4.7 and preemptive in 63.7% of cases. Right kidneys and multiple arteries were seen in 14.6% and 12.2%, respectively. Mean operative and rewarming time was 197±42 and 47±9.6 minutes, respectively. Five cases required conversion to open surgery because of abnormal kidney vascularization. Two patients required embolization for subcapsular and hypogastric artery bleeding without repercussion. Three kidneys were lost, two of them due to acute rejection and one because venous thrombosis. Late complications requiring surgery included one kidney artery stenosis, one ureteral stenosis, two lymphoceles, and three hernia repairs. We noticed a significant reduction in time between the first 20 cases and the following ones from 248.25±38.1 to 189.75±25.3 (p<0.05). With a mean follow-up time of 1.8 years (SD 1.3), the mean creatinine was 1.52 (SD 0.7) and RAKT graft survival was 98%. Conclusions. The robotic approach is an attractive, minimally invasive method for kidney transplantation, yielding good results. Further studies are needed to consider it a standard approach.
