Analysis of postoperative urinary incontinence and influencing factors of transurethral holmium laser enucleation of the prostate.

INTRODUCTION: To investigate the related factors of urinary incontinence after transurethral holmium laser enucleation of the prostate (HoLEP), and to provide guidance for clinical urinary control of HoLEP. METHODS: The clinical data of 548 patients who underwent HoLEP were retrospectively analyzed. The patients were followed up for the occurrence of urinary incontinence in the short term (2 weeks), medium term (3 months) and long term (6 months) after HoLEP. RESULTS: Among the 548 benign prostatic hyperplasia (BPH) patients, 79 cases (14.42%) had urinary incontinence at 2 weeks, 19 cases (3.47%) at 3 months and 2 cases (0.36%) at 6 months after surgery. Logistic regression analysis showed that age, prostate volume, diabetes mellitus, operation time, prostate tissue weight and histological prostatitis were risk factors for recent urinary incontinence (P<0.05). Age, diabetes and operation time were risk factors for mid-term urinary incontinence (P<0.05). The incidence of long-term urinary incontinence was low and no risk factor analysis was performed. CONCLUSIONS: For good urinary control after HoLEP, in addition to surgery-related factors such as surgical skills, proficiency and precise anatomy, patients' risk factors should also be paid attention to in order to improve postoperative urinary control more effectively and reduce the incidence of urinary incontinence.

Synthesis and Luminescence Properties of a Novel Yellow-White Emitting NaLa(MoO4)2: Dy3+, Li+ Phosphor.

Intense yellow-white NaLa(MoO4)2: Dy3+ phosphors co-doped with Li+ ions have been successfully synthesized via facile sol-gel combustion approach. The dependence of the crystal structure and crystallinity, particle morphology, photoluminescence property, fluorescent lifetime and absolute quantum efficiency of the as-prepared phosphors has been investigated. Stable yellow-white emission from 440 nm to 600 nm and higher absolute quantum efficiency were studied on Dy3+ doped NaLa(MoO4)2, Dy3+ and Li+ co-doped NaLa(MoO4)2, respectively. Surprisingly, only a small amount of Li+ can lead to a remarkable increase of the PL intensity and the quantum efficiency. Especially, along with 0.75 mol% Li+ ions induced in the NaLa(MoO4)2: Dy3+ phosphors, the absolute quantum efficiency increased from 13.8% to 22%, and the possible mechanism has been deeply discussed. Outstanding luminescence properties have certified that NaLa(MoO4)2: Dy3+, Li+ phosphors are promising candidates as new yellow-white components for optical devices.
