Purpose: To investigate the clinical efficacy of nephroscopic laser lithotripsy with the aid of a patented suctioning sheath in treating complicated whole-liver dispersed intrahepatic ductal stones. Methods: From September 2013 to September 2017, 150 patients who were diagnosed with whole-liver dispersed intrahepatic ductal stones were included in this study and were divided into two groups randomly. The control group consists of 75 patients who were treated by traditional surgery combined with choledochoscopic laser lithotripsy. The observation group consists of the other 75 patients who were treated by traditional surgery combined with nephroscopic laser lithotripsy with the aid of the patented sheath. Related treatment outcome parameters were compared. Results: There were no significant differences in first surgery operative time, first surgery bleeding amount, complication and stone clearance rates (P>0.05). However, the second surgery operative time was (63.58±9.84) min while the complication rate was 7.5% in the observation group, significantly less than that of control group (P<0.05). There were significantly higher first-stage and second stage sinus ductal stone clearance rates and final stone clearance rate in the observation group compared to that of control group (P<0.05), while operative times, hospitalization duration and cost, and one year stone recurrent rate were significantly lower (P<0.05). Conclusion: The efficacy of using the patented stone-clearance sheath combined with nephroscopic holmium laser lithotripsy was significant, warrants more extensive clinical adoption.

Tract Infections

Pyelovesical bypass devices or artificial ureters have been described as a last resort in patients with long ureteral strictures that fail traditional endoscopic and open repair. Herein, we describe a 52-year-old female who had a Detour (Coloplast, Humlebaek, Denmark) pyelovesical bypass device inserted after an iatrogenic ischemic injury to the distal two-thirds of the left ureter during pelvic surgery for recurrent endometrial stromal sarcoma. Six months after placement of the device, she presented with gross hematuria and recurrent urinary tract infections (UTIs) and was found to have encrustation of the distal silicone tip of the Detour device within the bladder. This was managed with resection of the distal silicone tip and flexible ureteroscopy with holmium laser lithotripsy. Despite suppressive antibiotic therapy and medical therapy for hypercalciuria, she presented four years later with intraluminal encrustations in the proximal end of the device. This was successfully managed with flexible ureteroscopy with holmium laser lithotripsy. Therefore, this case illustrates the feasibility of flexible ureteroscopy and holmium laser lithotripsy of Detour device encrustations as long as the device is not kinked and it allows the passage of the flexible ureteroscope up to the calcifications. In addition, patients contemplating insertion of such devices should be counselled regarding the risk of recurrent infections and encrustations.

Staghorn Stones

Conservative treatment is closely associated with renal deterioration for patients with renal staghorn stones. It is well-recognized that percutaneous nephrolithotomy (PCNL) is recommended as the first-line treatment of renal stones larger than 2 cm due to its higher stone clearance and cost-effectiveness when compared with other treatment alternatives, such as shockwave lithotripsy and flexible ureteroscopy (FURS). Besides, our findings indicated that miniaturized PCNL could be served as an alternative to PCNL with a higher stone-free rate and a lower hemorrhage risk. Despite the higher cost-effectiveness of PCNL, the management of staghorn stones are still controversial in some special situations, such as a solitary kidney. Herein, we present a case with complex infectious stones of a right-sided solitary kidney, complaining of persistent pain in the right waist. The rarity of this case is that it is difficult to encounter these cotton-like staghorn stones which are clinically resistant to holmium laser lithotripsy, and the particularity is that the patient with solitary kidney failed to undergo PCNL. We found that the combination of intermittently high-frequency oscillation and flexible ureteroscopy forceps might contribute to treat the complex infectious stones in a patient with solitary kidney. Our surgical experience might be beneficial to such patients undergoing flexible ureteroscopy in clinical practice.
