“…Almusafer and Al-Tawri (27) found that 11 out of 18 patients (57.9%) who received SWL before URS, suffered ureteral mucosa abrasions, while Fuganti et al (28), on a cohort of 1,235 ureteroscopies, reported an almost similar percentage of minor ureteral lesions, namely 61.8%. A study conducted by Ogreden et al (29) on early URS for distal ureteral stones highlighted the efficiency of this procedure in experienced hands with rather low complication rates, similar to our study. Therefore, significant discrepancies regarding the reports on this type of complication should be investigated.…”

Introduction: Urolithiasis is an increasing health problem worldwide including developing countries like Nepal. Ultrasonography and computed tomography of kidney, ureter and urinary bladder imaging modalities are used in detection of urolithiasis. This study was done to compare ultrasonography and computed tomography of kidney, ureter and urinary bladder findings for detection of urolithiasis. Methods: A cross-sectional study was conducted in Department of Radiology, Gandaki Medical College, Pokhara, Nepal from July to October, 2021 after obtaining ethical clearance from Institutional Review Committee of Gandaki Medical College. Total 92 patients who had urolithiasis in computed tomography and had ultrasound report available within one week were selected for the study. Demographic data of patients, location and side of calculi were recorded. The findings of ultrasonography and computed tomography were then compared. Similarly, sensitivity and specificity of ultrasonography were calculated. Results: Urolithiasis was more common in middle age groups i.e. 20 to 40 years (n= 57, 62.0%) and in males (n=56, 60.9%). Kidney was the commonest location detected by both ultrasonography (n=45, 48.9%) and computed tomography (n=44, 47.8%) with predominance in right side. Some of the calculi that were undetected by ultrasonography were easily confirmed by computed tomography in various locations. This was found to be statistically significant (p<0.05). The sensitivity and specificity of ultrasonography in compared to computed tomography was 83.7% and 100% respectively. Conclusions: Ultrasonography has poor sensitivity and high specificity for detecting urolithiasis. Thus, computed tomography can be considered as better imaging modality as compared to ultrasonography for diagnosis of urolithiaisis.

“…While decompression of the upper urinary tract via ureteral stenting or nephrostomy is the treatment of choice for initial concomitant infection, early ureterorenoscopic stone removal could be performed in patients with impaired renal function or refractory pain instead of primary decompression followed by secondary stone removal. Particularly in the case of small distal stones, which is a predisposing factor for concomitant perirenal stranding, an early ureterorenoscopic stone removal seems to be accompanied by only few infections and complications [ 18 , 19 ].…”

Is conservative management safe in patients with acute ureterolithiasis and perirenal stranding?

In patients presenting with ureterolithiasis, perirenal stranding is frequently observed in non-contrast computed tomography. Because perirenal stranding may be caused by tears in the collecting system, previous studies have described an increased risk of infectious complications and suggested broad empiric antibiotic therapy and immediate decompressing of the upper urinary tract. We hypothesized that these patients can also be managed conservatively. Therefore, we retrospectively identified patients with ureterolithiasis and perirenal stranding and compared diagnostic and treatment characteristics as well as treatment outcomes between patients undergoing conservative versus interventional management by ureteral stenting, percutaneous drainage or primary ureteroscopic stone removal. We classified perirenal stranding as mild, moderate or severe based on its radiological extent. Of 211 patients, 98 were managed conservatively. Patients in the interventional group had larger ureteral stones, more proximal ureteral stone location, more severe perirenal stranding, higher systemic and urinary infectious parameters, higher creatinine levels, and received more frequent antibiotic therapy. The conservatively managed group experienced a spontaneous stone passage rate of 77%, while 23% required delayed intervention. In the interventional and conservative groups, 4% and 2% of patients, respectively, developed sepsis. None of the patients in either group developed a perirenal abscess. Comparison of perirenal stranding grade between mild, moderate and severe in the conservatively treated group showed no difference in the spontaneous stone passage and infectious complications. In conclusion, conservative management without prophylactic antibiotics for ureterolithiasis and perirenal stranding is a valid treatment option as long as no clinical or laboratory signs of renal failure or infections are observed.
