Objectives: The objectives of this study were to study the efficacy of diode laser prostatectomy in patients infected with benign prostatic enlargement.Methods: A total of 62 men were included in our prospective clinical study from August 2017 to January 2018. The size of their prostates (ml) was ranged from 38 to 65, digital rectal examination for all patients was revealed the features of benign prostatic enlargement, prostate-specific antigen was ranged from 0.3 to 14 ng/ml, underwent laser prostatectomy (Diode laser).Results: The study included 62 men with 67.82±7.57 years. After the operation, the median maximum flow rate (Qmax) was increased 11–22 ml/s and the increment was highly significant (p<0.001), and median international prostate symptom score was highly significantly reduced from 19 to 10 (p<0.001). In addition, median residual volume was highly significantly reduced from 169.5 to 77 ml (p<0.001). Mean duration of operation was 67.82±7.57 min. The duration of catheterization with a mean of 1.16±0.45 days. Most patients required only 1 day of hospital stay postoperatively. No one developed post-operative bleeding, erectile dysfunction was reported in a single patient (1.6%), urinary incontinence in one patient (1.6%), and urinary tract infection was the most frequent post-operative complication being reported in 11.3%.Conclusion: Diode laser for the treatment of prostate is easily applicable, cheap and provides good ablation with low morbidity.

Initial Results

Objective: Our objective is to evaluate the efficacy, safety and 12 month outcome of a 980 nm diode laser with Twister fiber in the treatment of benign prostatic enlargement. Materials and methods: Between February 2011 and January 2013, 73 patients with benign prostatic enlargement had undergone diode laser vaporization of prostate at our institution. The following parameters were assessed at baseline, and after a follow-up period of 3 and 12 months: International Prostate Symptom Score, peak urinary flow rate, post-void residual urine volume, and quality of life score. Results: The procedure was completed successfully in all patients with no intraoperative complications. At 12 months postoperatively the percentage improvements in IPSS was-69.09%, Qmax +197%, PVR-88.54%, and QoL-68.29%. Conclusion: Diode laser vaporization of prostate is safe and effective method for treatment of benign prostatic enlargement.

AbstractPurposeA retrospective study was performed to describe and characterize a previously unreported finding on T2-weighted magnetic resonance imaging (MRI) of peripheral zone enlargement (PZE) associated with total prostatic enlargement without necessary association with benign prostatic hyperplasia (BPH) or lower urinary tract symptoms.MethodsT2-weighted MRI were reviewed from 2012-2018. Patients were referred for elevated serum prostatic specific antigen (PSA) levels, prostatic enlargement, or abnormal digital rectal examination (DRE) suggestive of adenocarcinoma. Enlargement of the thickness of the peripheral zone (PZ) was defined as a measurement of postero-lateral thickness (PLPZ) of ≥ 15.8 mm in the maximal transaxial plane. Endorectal coils were used in 2 patients. Microscopic pathology was described in 3 patients.ResultsThere were 22 patients who met the criteria out of 2871 subjects (<1%). Mean age was 63 years, Mean PLPZ was 17.7 mm (CI=0.45, range, 15.8-21.3). mean total prostatic volume was 55.1 cc (range, 19.9-127.2 cc), mean transition zone volume was 20.6 cc (range, 2.7-71.9 cc), mean transition zone index (TZI) was 0.34 (range, 0.31-0.68), mean prostatic specific antigen (PSA) was 13.9 ng/mL (range, 0.28-144.7), mean body mass index was 28.9 (range 23.0-36.3).. Enlargement was described in 14 of 20 (70%). Pathological findings showed marked glandular distention and atrophy with interstitial edema and chronic inflammatory cells. Significance of these results is discussed.

Background and ObjectiveThe thulium laser surgery is a relatively new approach in which a wavelength of approximately 2 μm is emitted in continuous-wave mode, thus enabling the precise incision of tissue by using a wavelength that matches the water absorption peak of 1.92 μm in tissue. However, no published multinational study or other evidence definitively declares the superiority of thulium vaporization (ThuVAP) over thulium vapoenucle-ation (ThuVEP) without morcellator for better management of bothersome benign prostatic hyperplasia. The present study aims to evaluate the efficacy of vaporization and vapoenucleation (without a morcellator) in thulium laser prostatectomy for the treatment of benign prostatic hyperplasia.MethodsA retrospective analysis of 82 patients who underwent thulium laser prostatectomy between February 2017 and January 2018 with ThuVAP and ThuVEP techniques was done and outcome measures analyzed were International Prostate Symptom Score (IPSS), quality-of-life score (QoL), maximum flow rate (Q max), post-void residual (PVRU), total operating time, laser time and resected tissue weight.ResultsNo significant differences were noted between ThuVAP and ThuVEP in terms of post-operative prostate volume (22.4 vs. 21.7 mL) and post-operative prostate specific antigen (PSA) (2.54 vs. 1.85 ng/mL). Nonetheless, there were differences between the groups in total lasing time (56.5 vs. 44.8 min, p = 0.001) and total operative time (88.5 vs. 71.5 min, p= 0.001). There was also a significant difference in IPSS, QoL score, Q max, and PVRU at 6 weeks, 3 months, 6 months and 9 months after surgery.

Benign prostatic enlargement (BPE) is an increase in the volume of the prostate gland which can be detected by digital rectal examination (DRE) or more accurately by transrectal ultrasound (TRUS). BPE may be due to benign prostatic hyperplasia (BPH) which is a histological diagnosis characterized by a combination of atrophy and proliferation in both glandular and stromal tissue. The onset of BPH is dependent on the presence of testes and increasing age. The first pathological signs appear under the age of 40 years followed by a rapid increase in prevalence with age: 80% of 80-year-olds have evidence of BPH. Bladder outlet obstruction (BOO) is defined by pressure-flow studies (PQS) and may be due to benign prostatic obstruction (BPO).
