“…It is reported that the prevalence of urolithiasis has been markedly increasing, in parallel to the environmental factors such as dietary habits and lifestyle which reflect the rising in living standard [2]. The stone composition also has changed during the period [3].…”

antidiabetic drugs (metformin) for sugar control, and the latest hemoglobin A1c test showed a value of 6.6 % (The American Diabetes Association suggests diabetes patients controlled their hemoglobin A1c value below 7 %). Benign prostate hyperplasia was treated by the α-adrenergic blockers (Doxaben ® ). According to the patient, the lower urinary tract symptoms got improved after the oral medications. He was never a smoker and denied gouty arthritis. Body mass index (BMI) revealed 26.13 kg/m 2 . His family had no history of either kidney stones or metabolic disorders. Based on these findings, transurethral cystolithotripsy was performed and the result was unexpected. There were total 1050 stones inside the bladder (Fig. 2). Cystolithotripsy was mainly evacuation of all stones without crushing the stone. Infrared spectroscopic analysis of urinary stones showed a curve resembling for uric acid. The uric acid value of urine and serum were 40.6 and 6.2 mg/dL, respectively (normal range of the random urine uric acid was between 16.8 and 50.4 mg/dL, and the serum uric acid value was between 3.1 and 8.3 mg/dL in male). His urine pH value was 5.4. After the operation, the lower urinary tract symptoms all got improved and the patient was doing well.

“…Both transurethral and percutaneous approaches have been proved efficient for bladder stone management (16)(17)(18). Miller et al tested stone extraction by percutaneous CYS using the EndoBag Entrapment sac (US Surgical, Norwalk, CT) in a prospective study comprising patients with augmented bladders (17).…”

“…The entrap- ment sac perforated in 1 of 4 cases due to disproportional sac and stone dimensions, which led the authors not to recommend its use when adjuvant lithotripsy is required. Lam et al tested the same device and used ultrasonic lithotripsy in 8 patients with large calculi (mean size of 41 mm) (18). All patients were rendered stone free after a single procedure and the device was considered safe.…”

Purpose: to test the effect of stone entrapment on laser lithotripsy efficiency. Materials and Methods: Spherical stone phantoms were created using the BegoStone® plaster. Lithotripsy of one stone (1.0g) per test jar was performed with Ho:YAG laser (365µm fiber; 1 minute/trial). Four laser settings were tested: I-0.8J,8Hz; II-0.2J,50Hz; III-0.5J,50Hz; IV-1.5J,40Hz. Uro-Net (US Endoscopy) deployment was used in 3/9 trials. Post-treatment, stone fragments were strained though a 1mm sieve; after a 7-day drying period fragments and unfragmented stone were weighed. Uro-Net nylon mesh and wire frame resistance were tested (laser fired for 30s). All nets used were evaluated for functionality and strength (compared to 10 new nets). Student's T test was used to compare the studied parameters; significance was set at p < 0.05. Results: Laser settings I and II caused less damage to the net overall; the mesh and wire frame had worst injuries with setting IV; setting III had an intermediate outcome; 42% of nets were rendered unusable and excluded from strength analysis. There was no difference in mean strength between used functional nets and non-used devices (8.05 vs. 7.45 lbs, respectively; p = 0.14). Setting IV was the most efficient for lithotripsy (1.9 ± 0.6 mg/s; p < 0.001) with or without net stabilization; setting III was superior to I and II only if a net was not used. Conclusions: Laser lithotripsy is not optimized by stone entrapment with a net retrieval device which may be damaged by high energy laser settings.

A Hybrid Treatment for Large Bladder Stones: Laparoscopic Cystolithotomy with Combined Direct Visual Lithotripsy

There are diverse surgical methods for treating large bladder stones, such as transurethral cystolithotripsy (TUCL), percutaneous suprapubic cystolithotripsy (PCCL), open surgery, and laparoscopic methods. We report here a case of two large bladder stones treated by using a combined surgical method of a laparoscopic approach and direct visual lithotripsy. However, surgical methods using the laparoscopic method have not been reported so far. We report here a case of two large bladder stones successfully removed by using a hybrid method combining the benefits of laparoscopic surgery and lithotripsy. CASE REPORTA 55-year-old man was admitted with the chief complaints of voiding difficulty, sudden stoppage of urination, frequency of urination, and residual urine sensation, which he had experienced for the previous 5 years. A pelvic radiographshowed two large radiopaque densities in the bladder (Fig. 1).Flexible cystoscopy showed two yellow and round-shaped stones at the center position, and they were not stuck to each other or to the bladder wall.

Percutaneous Cystolithotomy of Large Urinary-Diversion Calculi Using a Combination of Laparoscopic And Endourologic Techniques

Abstract: Our technique of percutaneous cystolithotomy utilizing laparoscopic and endourologic instrumentation is safe and effective for the removal of large calculi from urinary diversions. It is well tolerated, allows complete stone removal in a single sitting, and obviates an open procedure.
