Special Issue Information

Dear Colleagues,

In recent decades, technological evolution has transformed surgical treatments in the urological and andrological field. This progress has led to increasingly less invasive and, at the same time, increasingly precise and accurate surgical strategies, thus obtaining better perioperative and functional outcomes. One of the examples of the technological evolution impact on urological and andrological surgery is represented by the application of laser surgery for the treatment of benign prostatic hyperplasia, lithiasis, as well as genital warts. Therefore, this Special Issue covers the following topics:

  • Evolution of laser therapy in urology;
  • Innovative laser surgical technique in urology;
  • New applications of laser therapy in urology.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Applied Sciences is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2400 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

Holmium laser enucleation of the prostate (HoLEP) is a valid alternative to transurethral resection of the prostate and open simple prostatectomy for the treatment of a larger prostate, demonstrating comparable efficacy and lower morbidity. One of the most bothersome symptoms after HoLEP is urinary incontinence (UI), which is present in almost 20% of patients, with a recovery rate of over 80% at 3 months. A relevant risk factor linked to UI is the damage of the external sphincter during the enucleation of adenoma tissue close to it. In our modified HoLEP technique named Cap HoLEP, we preserve the anterior prostate portion proximal to the external sphincter. This cap of adenoma could reduce mechanical stress and laser energy widespread on the sphincter, acting as a protective barrier. The aim of this study was to describe the Cap HoLEP technique and to evaluate its safety and efficacy by assessing peri-operative and functional outcomes. We enrolled all patients who consecutively underwent Cap HoLEP from December 2017 to October 2019 in our hospital. Baseline characteristics; the International Prostate Symptom Score; uroflow findings; intraoperative data, intraoperative, and postoperative complications; and UI were all assessed. The median operative time was 122 min with 138 kJ of laser energy delivered. Median ∆Hb was 0.8 gr/dL. Seven low-grade complications were recorded. At 1 month, 34.8% of patients presented UI, 16.7% urge incontinence, 13.6% stress incontinence, and 4.5% mixed incontinence. At 3 months, UI showed a significant improvement, decreasing to 12.1%. At 6 and 12 months, UI was 7.6% and 3%, respectively. Our modified HoLEP technique is safe and effective, allowing significant improvement in the postoperative UI rate. Full article

Thulium fiber laser with a wavelength of 1.94 µm is widely used in urology for lithotripsy. This paper studies the mechanism of lithotripsy and evaluates its clinical efficiency using the superpulse thulium fiber laser with a wavelength of 1.94 µm and a peak power of 500 W. An experimental setup was developed to study the mechanism of lithotripsy. The superpulse thulium fiber laser (TFL) with a wavelength of 1.94 µm with a peak power of 500 W (FiberLase U2 from “IRE-POLUS” Ltd., Fryazino, Moscow Region, Russia) was used for the lithotripsy of stone phantoms (BegoStone). The processes were recorded with a high-speed camera. The acoustic signals registered during lithotripsy were studied with wideband and needle hydrophones. The main mechanism of lithotripsy performed by using superpulse TFL was thermal cavitation in the water-filled pore space and thermal destruction of the phantom. During the clinical application of the superpulse thulium fiber laser, the high efficiency of laser lithotripsy was established. The performed optical and acoustic studies showed that the mechanism of the destruction of stones was based on the synergic effect of the explosive boiling of water in the pore space of the stone, and its thermal destruction is associated with the heating of the stone to several hundred degrees with laser radiation.
