Influence of the laser pulse shape in the treatment of stones in the upper urinary tract

Purpose: Urinary stones can be successfully treated using a Holmium: Yttrium-Aluminum-Garnet (Ho: YAG) laser. Regarding success rates, laser pulse energy, frequency, and pulse width are well-known contributing factors. Whether the pulse shape might be a further factor influencing the laser efficiency is unclear. This study aimed to evaluate different modes of laser pulse shapes in a real-world setting. Materials and Methods: The Dornier Medilas® H Solvo (Weßling, Germany) was used in the treatment of ureter and kidney stones. Patients were randomized into standard pulse shape (SPS) and new pulse shape groups (NPS1; ureter) and (NPS2; kidney pelvis), depending on the stone localization. The primary endpoint was laser efficiency defined as mm3 stone destruction per overall operating time. Secondary endpoints encompassed number of stone recoveries and stone-free rate. Results: Altogether 145 patients (24 SPS vs. 32 NPS1; 51 SPS vs. 38 NPS2) were included. No differences in sex, age, body mass index, stone localization and stone composition were found, except for preoperative stone size (133±95 [SPS] vs. 197±139 [NPS1] mm3; p=0.023) and (348±298 [SPS] vs. 525±429 [NPS2] mm3; p=0.042). Regarding the primary endpoint, a significant increase in laser efficiency could be detected for the NPS1 and NPS2 groups compared to the SPS groups (39.9±44.9 vs. 28.8±30.2 and 51.7±61.3 vs. 22.4±24.2 mm3/min [mean±standard deviation]). No statistically significant differences were found for secondary endpoints and perioperative complication rates. Conclusions: Efficiency of the Ho: YAG laser can be positively influenced by different pulse shapes. This adds the variable of individualized intraoperative decision making.

Purpose: To report a single surgeon experience with one year follow-up after open ureteroplasty with buccal mucosa graft (OUBMG) in the rare situation of long segment proximal ureteral strictures. Materials and Methods: Four patients with long segment proximal ureteral stricture underwent OU-BMG between February and July 2017. Functional outcome was assessed by pre- and postoperative serum creatinine, ultrasound and renal scintigraphy as well as patient reported outcomes. Results: Four patients with an average stricture length of 4 cm underwent OU-BMG between February and July 2017. No major postoperative complications occurred. Retrograde uretero-pyelography 6 weeks postoperatively revealed a watertight anastomosis followed by immediate emptying of the renal pelvis and ureter in all four patients. Ureteroscopy at this time showed a wide lumen with well-vascularized pink mucosa. After a mean follow-up time of 12.5 (12–14) months, postoperative serum creatinine was unimpaired. Renal scintigraphy revealed no signs of renal obstruction. With regard to intraoral surgery, no difficulties with mouth opening or intraoral dryness or numbness were reported. Conclusions: For patients with long segment ureteral strictures OU-BMG is a safe technique with excellent surgical and functional outcomes. Hence, the application of this technique should be encouraged and regarded as one of the standard options in case of this rare problem.

Purpose: To evaluate long-term outcomes of AdVance and AdVanceXP male slings in patients with persistent stress urinary incontinence (SUI) after transurethral resection of the prostate (TURP). Methods: A total of 18 consecutive patients received AdVance (n=14) or AdVanceXP (n=4) male sling implantation between 2007 and 2013. Continence was determined by pad use, 24-hour pad testing and validated questionnaires (International Consultation on Incontinence Questionnaire Short Form, ICIQ-SF). Quality of life was evaluated by International Quality of Life (IQoL) score. Patient satisfaction was measured with patient’s global impression of improvement score. Cure was defined as 0–5 g in the 24-hour pad test. Statistical analysis included Fisher exact and Wilcoxon test (P<0.05). Results: Follow-up was available for 15 patients who underwent further analysis. After a median follow-up of 70 months (range, 18–83 months), mean daily pad usage was 1.8±2.1 pads (P=0.015 vs. baseline level). Mean IQoL score was 66.4±31.6 (P=0.050 vs. baseline level), and mean ICIQ-SF score was 9.5±6.6 (P=0.077 vs. baseline level). Based on 24-hour pad testing, mean daily urine loss was 31.2±64.5 g (median, 0 g; range, 0–209 g). Cure rate was 46.7%, and cure-and-improved rate was 60.0%. Assessing predictive features for success, better results were found in patients who needed up to 4 pads preoperatively (P=0.041) as well as for patients ≤71 years at the time of implantation (P=0.041). Conclusions: The findings indicate that AdVance and AdVanceXP implantation can be performed effectively and safely in men suffering from SUI after TURP. However, long-term success rates seem to be lower compared to SUI after radical prostatectomy and patients should be counseled accordingly.
