OBJECTIVES: The conventional Fr26 resectoscope is difficult to use in patients with benign prostatic hyperplasia (BPH) complicated by urethral stricture. This study aims to evaluate the safety and efficacy of transurethral plasmakinetic resection of the prostate (PKRP) using a small-caliber (Fr18.5) plasmakinetic resectoscope combined with urethral dilation in patients with BPH and mild urethral stricture. METHODS: A retrospective analysis was conducted on 37 patients with BPH and mild urethral stricture treated at the Department of Urology, Hunan Provincial People's Hospital from January 2023 to December 2023. All patients underwent PKRP with a small-caliber plasmakinetic resectoscope, followed by routine placement of a Fr20 three-way Foley catheter for continuous bladder irrigation. International Prostate Symptom Score (IPSS), maximum urinary flow rate (Q_max), post-voiding residual urine volume (PVR), and Quality of Life (QOL) scores were compared before and after surgery. Perioperative indicators (intraoperative bleeding, operative time, postoperative catheterization time, and postoperative hospital stay) and complications were recorded. RESULTS: The median age was 69 years, and the median duration of voiding difficulty was 36 months. Median total prostate specific antigen (T-PSA) was 2.095 ng/mL, free prostate specific antigen (F-PSA) 0.561 ng/mL, and F/T ratio 0.3. Median prostate diameter was 48 mm and volume 41 mL. All 37 surgeries were completed successfully: 11 had external meatal stricture, 19 had mild anterior urethral stricture, and 7 had mild posterior urethral stricture (1 patient with a 1 cm pseudo-blind tract near the membranous urethral). Operative time was (2.4±0.7) hours, blood loss was (40±29) mL, median catheterization duration was 7 days, and median hospital stay was 7 days. No cases of postoperative urinary incontinence, recurrent hematuria, or sepsis occurred, and patients were satisfied with the surgical outcome. At 3 to 6 months follow-up, IPSS, Q_max, PVR, and QOL scores significantly improved compared to preoperative levels (all P<0.01), with no cases of urethral stricture progression or new-onset stricture. CONCLUSIONS PKRP using a small-caliber plasmakinetic resectoscope is safe and effective for treating BPH with mild urethral stricture. It offers advantages such as minimal trauma, rapid postoperative recovery, and a lower risk recovery, and a lower risk of aggravating urethral injury.

Objective To analyze the immunostimulatory effects of cyclic dinucleotides ( CDN) on immune responses to a nasal spray influenza split virus vaccine and to evaluate its potential as a mucosal ad-juvant. Methods A H1N1 influenza split virus vaccine combined with different CDN was used for mouse immunization. Each mouse was intranasally immunized twice with 4. 5μg of hemagglutinin (HA) and 10μg of CDN with an interval of 21 d. Titers of hemagglutination inhibition ( HI) antibodies in serum, secretory IgA ( sIgA) in bronchoalveolar lavage fluid and IgG in serum were detected 21 d after the last immunization. Immunostimulatory activities of different CDN were compared. Effects of cyclic di-GMP ( c-di-GMP) and ch-itosan (CSN) on the immunogenicity of H1N1 and H7N9 influenza split vaccines were analyzed and com-pared. H1N1 influenza split vaccine combined with c-di-GMP or CSN was used to immunize mice. Three weeks after the last immunization, these mice were challenged with 10 times the median lethal dose ( LD50 ) of A/Puerto Rico/8/34 (H1N1) influenza virus. Survival rates of the mice were observed for 14 d. Results All three CDN induced high levels of HI antibodies and IgG in serum and sIgA in BALF. HI antibody sero-conversion rates were also higher than those of the control groups. c-di-GMP was superior to CSN in enhan-cing the immunogenicity of H1N1 and H7N9 antigens as higher titers of HI antibodies in serum and sIgA in BALF were induced. Conclusions CDN could enhance the immunogenicity of influenza antigens with better efficacy than CSN adjuvant.
