Retrograde ureteric stone migration is an extremely rare phenomenon with only one previously reported case in the literature. We report on a case of upward spontaneous migration of a ureteric stone in a 39-year-old male military trainer in Saudi Arabia who was diagnosed with upper left ureteric stone based on non-contrast spiral computerized tomography kidney ureter bladder (CT-KUB) scan. The plan was to treat the patient conservatively with alpha blockers and oral hydration. Two weeks after treatment started, repeated CT-KUB scan revealed an upward migration of the stone to the left renal calyx. Accordingly, we highly recommend performing a prior stone localizing imaging test to avoid unnecessary procedures or operations.

“…Despite being a small study (n = 24), a major strength was that only stones that had spontaneously discharged were included allowing for manual measurement. Another study compared ureteral stone measurements in 60 patients using both the soft tissue and bone windows in multidetector CT [15]. The average stone size in the bone window was 4.8 mm, while in the soft tissue window, it was 6.68 mm.…”

Purpose: Low-dose computer tomography (NCCT) is the standard imaging modality for patients with acute flank pain with a suspicion of urolithiasis. The stone size is usually measured 2D by a radiologist. We compared 3D stone measurement using different windows to the 2D measurement and evaluated the clinical impact on ureterorenoscopic stone removal (URS). Methods: One hundred sixty-four patients (201 stones) with a preoperative NCCT, following a URS within 4 weeks, were included in this study. Stone location, number and size of stones, operating time, and laser lithotripsy were documented. Stones were measured in 3D using bone and soft tissue window. The maximum diameter was compared to the radiological report. The U test, Kruskal-Wallis, and regression were used for statistical analyses. Results: Almost two-thirds (64.68%; 130 stones) of stone measurements in 3D with the bone window were lower than the radiologist reports in 2D. One-third (34.83%; 70 stones) of stone measurements were higher and 0.5% (1 stone) reported the same size. Using the 3D soft tissue window, 81.09% (163 stones), 17.91% (37 stones), and 1% (2 stones) of stones were measured bigger, smaller, or had the same measurement results, respectively. In the clinical setting, we could calculate a cutoff for laser lithotripsy at a maximum stone diameter of 5.70 mm (p < 0.01) with the 3D and 6.01 mm with the 2D measurements, respectively, and found a significant correlation between maximum stone diameter and operating time (p < 0.01) and number of stones and operating time (p < 0.01 with and p = 0.02 without laser). Conclusion: 3D stone measurement with bone window seems to be more accurate than 2D measurement, but 2D is sufficient for planning stone treatment.

“…3 The stone site has a major impact on the symptoms of acute renal colic. 4 Over decades, great advances have been made in the minimally invasive treatment of ureteral stones. [5][6][7] Recent therapeutic options include transurethral lithotripsy (TUL) by holmium laser, extracorporeal shock wave lithotripsy (ESWL) for proximal ureteral stones, and laparoscopic lithotripsy.…”

“…[10][11][12] Stone removal with ureteroscope is most effective in treating lower ureteral stones. 4 In the setting of acute ureteral colic, ureteral spasms make the passage of the guide wire of the ureteroscope difficult. 5 However, applying local lidocaine gel, aminophylline 5%, or intravenous Buscopan® can reduce ureteral spasms and increase the rate of successful ureteroscopy.…”

The Effect of Propofol on the Success Rate of Transurethral Lithotripsy by Holmium Laser: A Randomized Clinical Trial

et al. 2020

Introduction: Urinary stone disease is the third most common affliction of the urinary tract that has been associated with an increasing incidence. Over decades, great advances have been made in the minimally invasive treatment of urinary stones. Recently, transurethral lithotripsy (TUL) by holmium laser was introduced as a possible therapeutic option. This study evaluated the effect of propofol on the success rate of TUL by holmium laser. Methods: A double-blind randomized controlled trial was conducted on 180 patients to investigate the effect of propofol on the success and complication rate of TUL by holmium laser. The enrolled patients were divided into two groups: the first group received sodium thiopental (n=89) while the second group received propofol (n=91). The two groups were compared in terms of the fluctuations of systolic blood pressure (SBP), diastolic blood pressure (DBP), heart rate (HR), operation time, future stone-free rate (SFR), stone migration, post-operative fever, and ureteral complications such as perforation and mucosal damage. Other developed complications were also recorded. After data gathering, statistical analysis was performed with SPSS version 21. Results: the patients’ data such as age, sex, stone diameter, stone laterality, duration of stone impaction, primary SBP, DBP and HR were not significantly different between the two groups (P>0.05). TUL and anesthesia duration, first-minute and fifth-minute SBP and DBP, and also changes of HR were significantly lower in the propofol group compared with the sodium thiopental group (P<0.001). Moreover, SFR of TUL was more evident in the propofol group. Ureteral mucosal damage was significantly less in the propofol group. Conclusion: Propofol was associated with a higher reduction in SBP and DBP, decreased duration of TUL, fewer fluctuations in HR, and an increased success rate of stone removal by TUL with holmium laser.
