Reconstruction of fossa navicularis stricture (FNS) poses a challenge in providing acceptable functional and cosmetic outcomes. We describe our novel surgical technique and its short-term results.
This urethroplasty technique is a single-stage dorsal inlay buccal mucosal graft placement with subcoronal vertical sagittal ventral urethrotomy without glansplasty. Twenty-one operated patients were followed up at 2 months and 6 months postoperatively. We studied the functional outcome of the International Prostate Symptom Score, quality of life (QoL) score, maximum flow rate, postvoid residual (PVR) urine, and reconstructed urethral luminal caliber. Sexual function was studied via a brief male sexual function inventory. Hypospadias objective score evaluation (HOSE) was used to assess the cosmesis. Patient satisfaction was evaluated using the global response assessment score (GRA).
FNS is seen commonly associated with lichen sclerosus (n = 12). Nine patients had stricture that extended into the distal penile urethra. The mean stricture length was 2.76 cm. At the end of the study, a significant improvement in mean IPPS (18.81), mean QoL score (2.25), mean Q (20.94 mL/s), mean PVR (103.05 mL), and mean urethral caliber (16.06 Fr) were noted. No difference in sexual drive and erectile function but significant improvement in ejaculation was noted. All patients had single-stream urine, reconstructed urethral caliber ≥16Fr, HOSE ≥14, and GRA ≥2 at 6 months. Except for two patients, all had vertical slit-like meatus.
This technique is feasible, with good cosmetic, functional, and subjective outcomes with marked patient' satisfaction.
舟状窝狭窄(FNS)的重建在实现可接受的功能和美容效果方面具有挑战性。我们描述了我们新颖的手术技术及其短期结果。
这种尿道成形术技术是单阶段背侧嵌入颊黏膜移植,同时进行冠状下垂直矢状腹侧尿道切开术,不进行龟头成形术。21例手术患者在术后2个月和6个月进行了随访。我们研究了国际前列腺症状评分、生活质量(QoL)评分、最大尿流率、残余尿量(PVR)以及重建尿道腔内径的功能结果。通过简短的男性性功能量表研究性功能。采用尿道下裂客观评分评估(HOSE)来评估美容效果。使用整体反应评估评分(GRA)评估患者满意度。
FNS常见于与硬化性苔藓相关的患者(n = 12)。9例患者的狭窄延伸至阴茎远端尿道。平均狭窄长度为2.76 cm。在研究结束时,平均国际前列腺症状评分(IPSS)(18.81)、平均QoL评分(2.25)、平均尿流率(Q)(20.94 mL/s)、平均残余尿量(PVR)(103.05 mL)和平均尿道腔内径(16.06 Fr)均有显著改善。在性欲和勃起功能方面无差异,但射精功能有显著改善。所有患者在6个月时均有单股尿流、重建尿道腔内径≥16Fr、HOSE≥14且GRA≥2。除2例患者外,所有患者均有垂直裂隙状尿道口。
该技术可行,具有良好的美容、功能和主观效果,患者满意度高。
