ABSTRACT
OBJECTIVE: To investigate the surgical techniques and clinical effect of Memokath transurethral spiral thermo-expandable prostatic stent (STEPS) implantation in the treatment of BPH. METHODS: From January 2017 to January 2018, 26 BPH patients underwent Memokath transurethral STEPS implantation, 9 under the flexible cystoscope and the other 17 under the rigid cystoscope. The patients were aged 62ï¼91 years old, with a prostate volume of 32ï¼78 ml, postvoid residual urine volume (PVR) of (67.3 ± 11.2) ml, maximum urinary flow rate (Qmax) of (6.3 ± 1.8) ml/s, and IPSS score of 26.7 ± 5.7. Eight of the patients had preoperative urinary retention, of whom, 6 received catheterization and 2 had undergone cystostomy for bladder fistula before STEPS implantation. RESULTS: The operations lasted 15ï¼30 minutes and were successfully completed in 24 cases while stent-shedding occurred in the other 2. Twenty-two of the patients achieved spontaneous urination immediately after surgery and 2 experienced bladder clot embolism. At 3 month after surgery, 24 of the patients showed significant improvement in PVR (ï¼»21.4 ± 7.7ï¼½ ml), Qmax (ï¼»18.3 ± 4.7ï¼½ ml/s) and IPSS (8.3 ± 2.1), and 13 exhibited no statistically significant difference from the baseline in the IIEF-5 score (14.1 ± 1.1 vs 14.3 ± 1.0, P > 0.05). At 12 months, all the patients were found with markedly improved urination but no adverse events except recurrent urinary tract infection in 2 cases. CONCLUSIONS: Memokath STEPS implantation, with its advantages of simple operation, high safety, definite effectiveness, non-influence on sexual function, is a new effective surgical option for the treatment of BPH.
