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.

Tomography Scan

Prostate cancer is one of the most common male malignancies, but it rarely metastasizes to the proximal ureter. We report a case of a 76-year-old man who presented with flank pain and lower urinary tract symptoms. Abdominal computed tomography scan revealed multiple filling defects at the middle of the left ureter, enlarged retroperitoneal lymph nodes, and probable psoas invasion. The patient underwent nephroureterectomy with excision of a cuff of bladder, and was found to have an adhesion between the middle part of left ureter and psoas intraoperatively. The pathological examination displayed positive immunohistochemical staining with prostate-specific antigen and prostate acid phostate, supporting the diagnosis of metastatic ureteral tumour from prostate cancer. In this case, periureteral soft tissue and ureteral muscular layer were infiltrated by metastatic tumour, whereas the mucosa was spared. The periureteral lymphatic pathway played an important role in the metastatic procedure of prostate cancer to the proximal ureter.

Buccal ureteroplasty is considered a rare operation in urology and the indications for its implementation are still not clearly defined. We have described a clinical case of successful replacement of a part of the proximal ureter with a buccal graft in a patient with a single kidney, which was drained for a long time with a nitinol stent, which was subsequently incrustated, which led to the installation of a permanent nephrostomy drainage. The patient had no postoperative complications, the patency of the urinary tract was fully restored.

The objective: optimization of approaches to the choice of endoscopic ureterolithorpsy method in the presence of large stones of the proximal ureter. Materials and methods. For the period 2017–2020 y. the study included 136 patients with large stones of the proximal ureter, who were performed one of two methods of ureterolithotripsy: rULT (group I) or m-aULT (group II). In group I 73 (53,7%) patients were operated, in group II – 63 (46,3%) patients. The age of patients ranged from 18 to 81 years, the average age was 52,7 years (54±10,5). The age of patients in group II ranged from 25 to 77 (63±10,5) years; the size of a concrement from 10 to 20 (14±3,5 mm). In group I, the age of patients ranged from 18 to 91 (63,5±10 years); the size of a concrement from 7 to 20 (12±5,5 mm). Results. The average time of m-AULT was 58,5±15,4 min, while the status of stone free was achieved in all 100% of patients. The operation ended with the installation of nephrostomy drainage in 11 (17,5%) cases, nephrostomy drainage and internal ureteral JJ-stent – in 33 (52,4%), in 19 (30,2%) cases – tubeless drainage method with the installation of ureteral stent. And the total percentage of stenting in staghorn stones of the proximal ureter, after lithotripsy and litholapaxy was 82,6% (52 patients). RULT surgery in 92% (67 patients) of cases ended with drainage of the kidney by JJ-stent, in 6 (8%) patients the operation ended without drainage. Conclusions. Analyzing the results, it was noted that the antegrade approach is a safe and effective method of treatment for proximal ureterolithiasis in the group with large stones of the proximal ureter, where the effectiveness of RULT (SFR up to 86,3±3,9%) is significantly inferior to AULT, and minimizing the size of instruments m-aULT) reduces the number and degree of complications associated with the size of the coiled tract, while providing a high level of SFR (96,8±4,4%).
