Application of Percutaneous Holmium Laser Lithotripsy in the Treatment of Bladder Calculi with Lower Urinary Tract Obstruction or Pelvic Joint Disease.

The aim was to summarize the experience of percutaneous holmium laser lithotripsy in the treatment of bladder calculi with lower urinary tract obstruction or pelvic joint disease in our hospital, explore its efficacy and safety, and improve the minimally invasive surgical technique for bladder calculi. The clinical data of 61 patients with bladder calculi combined with lower urinary tract obstructive diseases, including urethral stricture, benign prostatic hyperplasia, and bladder neck contracture or pelvic joint diseases in our hospital from 2017 to 2019 were retrospectively analyzed. All patients with bladder stones measuring 1.5-9 cm were placed in supine or lithotomy position. B-scan was conducted to locate the puncture above the pubic symphysis, establishing a 16-30 Fr bladder channel, and Lumenis holmium laser lithotripsy was subsequently performed through a Li Xun Nephroscope. The crushed stones were flushed out through the percutaneous bladder channel or taken out with foreign body forceps. After surgery, the cystostomy tube was indwelled for 3 days. All the 61 cases were operated successfully with an average lithotripsy time of 25 min, and there was no conversion to open surgery. Postoperative reexamination showed neither residual calculi nor complications such as severe infection, massive hemorrhage, and intestinal injury. Percutaneous holmium laser lithotripsy is an improved minimally invasive surgical technique for the treatment of bladder calculi with the advantages of clear surgical field, high stone removal efficiency, less trauma, low-pressure bladder perfusion, and low incidence of accessory injury and infection. For patients with lower urinary tract obstructive disease resulting in obstruction of transurethral surgery and patients with pelvic joint disease resulting in difficult lithotomy position placement, this procedure is more advantageous than transurethral surgery. It is also suitable for bladder calculus with a long diameter >5 cm or multiple calculi.

Comparison of Ho:Yag laser and pneumatic lithotripsy combined with transurethral prostatectomy in high burden bladder stones with benign prostatic hyperplasia.

To compare the efficacy and reliability of Ho:YAG laser lithotripsy (HLL) and pneumatic lithotripsy (PL) in the treatment of bladder stones in patients with benign prostatic hyperplasia and stones ≥ 20 mm who were transurethrally treated in the same surgical session. We studied the data of patients with benign prostatic hyperplasia and ≥20 mm bladder stones who were treated with transurethral resection of the prostate and cystolithotripsy in the same session, obtained between January 2010 and February 2014 from three urology clinics. All patients underwent bipolar plasmakinetic (PK) transurethral resection of the prostate. For treatment of the bladder stone, either HLL or PL was applied. A total of 62 patients were divided into two groups: PK-PL (Group 1, n = 29) and PK-HLL (Group 2, n = 33). The data of both groups were analyzed for stone dimensions, stone fragmentation time, total operating time, hospitalization duration, prostate dimensions, success rates, and complications. Group 1 included 29 patients with a mean age of 70 ± 7.6 (range, 57-85) years, whereas Group 2 included 33 patients with a mean age of 67.5 ± 10.5 (range, 45-84) years. In Group 1, five patients had mucosa injury, one patient had residual stone, and one patient had bladder perforation. In Group 2, three patients had mucosa injury, three patients had postoperative fever, and one patient had residual stone. Total operation time and stone fragmentation time were significantly lower in Group 2 (p < 0.05). The remaining analyzed data were similar (p > 0.05). PK-HLL using a single shaft without the need for repeated access has the advantages of shorter fragmentation and operation time.
