OBJECTIVETo compare holmium laser enucleation (HoLEP) versus open prostatectomy (OP) for large volume benign prostatic hyperplasia.
METHODSThe randomized controlled trials (RCTs) pertaining to HoLEP and OP for management of large volume benign prostatic hyperplasia were retrieved from Medline and Embase. Meta-analysis was performed using Review Manager 5.0 software.
RESULTSThree RCTs were included in the analysis. No significant differences were found in IPSS or Qmax between HoLEP and OP (P>0.05). Compared with OP, HoLEP was associated with significantly less blood loss, a shorter catheterization time and a shorter hospital stay, but a longer operating time. HoLEP and OP were similar in terms of urethral stricture, stress incontinence, transfusion requirement and the rate of reintervention.
CONCLUSIONHoLEP and OP have similar therapeutic effects in the management of large volume benign prostatic hyperplasia. Although with a longer operating time and less resected tissue, HoLEP causes less blood loss and requires a shorter catheterization time and a shorter hospital stay. HoLEP has a comparable safety to OP in terms of the adverse events.

Dystrophic calcification can be defined as a calcification that occurs in degenerated or necrotic tissue. It is associated with multiple clinical conditions, such as collagen vascular diseases. It involves the deposition of calcium in soft tissues despite no generalized disturbance in the calcium or phosphorus metabolism, and this is often seen at sites of previous inflammation or damage. Potassium-titanyl phosphate (KTP) laser vaporization of the prostate is safe and relatively bloodless procedure that results in a shorter catheterization, immediate symptomatic improvement, and less severe postoperative irritative symptoms. However, longer follow-up studies or reports about complications are lacking. Here in we report a case of dystrophic calcification and stone formation on the entire bladder neck after performing KTP laser vaporization of benign prostate hyperplasia. That was treated by lithotripsy and transurethral resection.

A 21-year-old man presented with an enlarged giant hemangioma on glans penis which also causes an erectile dysfunction (ED) that partially responded to the intracavernous injection stimulation test. Although the findings in magnetic resonance imaging (MRI) indicated a glandular hemangioma, penile colored Doppler ultrasound revealed an invaded cavernausal hemangioma to the glans. Surgical excision was avoided according to the broad extension of the gland lesion. Holmium laser coagulation was applied to the lesion due to the cosmetically concerns. However, the cosmetic results after holmium laser application was not impressive as expected without an improvement in intracavernous injection stimulation test. In conclusion, holmium laser application should not be used to the hemangiomas of glans penis related to the corpus cavernosum, but further studies are needed to reveal the effects of holmium laser application in small hemangiomas restricted to the glans penis.

BACKGROUNDTransurethral resection of the bladder tumor (TURBT) remains the gold standard for non-muscle-invasive bladder cancer (NMIBC). Laser techniques have been widely used in urology. This analysis aimed to assess the safety and efficacy of holmium resection of the bladder tumor (HoLRBT) vs. TURBT.
METHODSA systemic search of MEDLINE, Embase, Web of Science, and The Cochrane Library as well as manual bibliography searches were performed to identify the relevant studies. The pooled estimates of operation time, obturator nerve reflex rate, bladder perforation rate, bladder irrigation rate, catheterization time, hospital stay, and one- and two-year recurrence free survivals were calculated.
RESULTSFive studies were enrolled into our meta-analysis. No significant difference was observed in the operation time between groups (weighted mean difference (WMD) 1.01, 95% confidential interval (95% CI) -3.52 - 5.54, P = 0.66). The significant difference in the obturator nerve reflex (OR 0.05, 95% CI 0.01 - 0.04, P = 0.004), bladder perforation (OR 0.14, 95% CI 0.03 - 0.61, P = 0.009), bladder irrigation (OR 0.13, 95% CI 0.04 - 0.45, P = 0.001), catheterization time (WMD -0.96, 95% CI -1.11 to -0.82, P < 0.00001), and hospital stay (WMD -1.46, 95% CI -1.65 to -1.27, P < 0.00001) showed advantages of HoLRBT over TURBT. The 2-year recurrence free survival rate favors the HoLRBT group (OR 1.46, 95% CI 1.02 - 2.11, P = 0.04).
CONCLUSIONSAs a promising technique, HoLRBT is safe and efficient, and showed several advantages over TURBT. HoLRBT can be used as an alternative procedure for TURBT in terms of low-grade papillary urothelial carcinoma or low-grade early TNM-stage urothelial carcinoma.

6.Urethral recovery after holmium laser enucleation of the prostate.
National Journal of Andrology 2018;24(2):99-103
Benign prostatic hyperplasia (BPH) is a common disease in the elderly population and holmium laser enucleation of the prostate (HoLEP) is an important method for its management. However, postoperative complications of HoLEP affects the patients' quality of life as well as the outcome of surgery. Based on the ten-year clinical practice and multi-center data analysis, the author puts forward the concept of "postoperative urethral recovery" for BPH patients receiving HoLEP, which involves postoperative pain recovery, urination recovery, urine control recovery, sexual function recovery, and a postoperative recovery system aiming at the acceleration of recovery.

A 32-year-old female who had undergone the silicone oil removal procedure presented with visual disturbance in her left eye. Several months previous, she had cataract surgery in a private clinic, and a month later she had a Nd:YAG laser procedure for posterior capsulotomy. The slit-lamp examination revealed silicone oil droplets that had adhered to the intraocular lens where the posterior capsulotomy was performed. She had experienced high myopia as a manifestation of the resulting refractive changes. We replaced the previous intraocular lens with a new acrylic intraocular lens with resulting improvement to her vision. Here we report the case of a female patient with a history of silicone oil removal surgery where the resulting silicone bubbles had not been removed thoroughly and remained in the vitreous cavity. These bubbles subsequently adhered to the intraocular lens following YAG laser posterior capsulotomy, resulting in refractive changes. We recommend that implanting a silicone intraocular lens in anyone with a history of the silicone oil removal procedure or who has a possible history of silicone oil use should be avoided.

PURPOSE: The thulium laser is the most recently introduced technology for the surgical treatment of benign prostatic hyperplasia (BPH). Until recently, most thulium laser enucleation of the prostate (ThuLEP) was performed by use of the three-lobe technique. We introduce a novel one-lobe enucleation technique for ThuLEP called the "All-in-One" technique. We report our initial experiences here. MATERIALS AND METHODS: From June 2013 to May 2014, a total of 47 patients underwent the All-in-One technique of ThuLEP for symptomatic BPH performed by a single surgeon. All patients were assessed with the International Prostate Symptom Score (IPSS), transrectal ultrasonography, serum prostate-specific antigen (PSA), maximal urine flow rate (Qmax), and postvoid residual urine volume (PVR) before and 1 month after surgery. We reassessed IPSS, Qmax, and PVR 3 months after surgery. To assess the efficacy of the All-in-One technique, we checked the PSA reduction ratio, transitional zone volume reduction ratio, and enucleation failure rate. RESULTS: The mean operative time was 82.1+/-33.3 minutes. The mean enucleation time and morcellation time were 52.7+/-21.7 minutes and 8.2+/-7.0 minutes, respectively. The mean resected tissue weight and decrease in hemoglobin were 36.9+/-24.6 g and 0.4+/-0.8 g/dL, respectively. All perioperative parameters showed significant improvement (p<0.05). No major complications were observed. The PSA reduction ratio, transitional zone volume reduction ratio, and enucleation failure rate were 0.81, 0.92, and 4.3%, respectively. CONCLUSIONS: The All-in-One technique of ThuLEP showed efficacy and effectiveness comparable to that of other techniques. We expect that this new technique could reduce the operation time and the bleeding and improve the effectiveness of enucleation.

OBJECTIVETo compare the effect and impact of holmium laser enucleation of the prostate (HoLEP) and 120-W thulium: YAG vapoenucleation of the prostate (ThuVEP) on erectile function in the treatment of benign prostatic hyperplasia (BPH).
METHODSWe retrospectively analyzed 93 cases of symptomatic BPH treated by HoLEP or 120 W ThuVEP. We made comparisons between the two groups of patients in the baseline and postoperative clinical and surgical indexes as well as their IPSS, quality of life (QOL), maximum flow rate (Qmax), postvoid residual urine volume (PVR), and IIEF-EF scores before surgery and during the 12-month follow-up.
RESULTSThuVEP, in comparison with HoLEP, achieved a significantly shorter operation time ([57.6 +/- 12. 8] vs. [70.4 +/- 21.8] min, P = 0.001) and a higher laser efficiency ([0.71 +/- 0.18] vs. [0.62 +/- 0.19] g/min, P = 0. 021). At 1, 6, or 12 months of follow-up, no significant differences were observed in IPSS, OOL, Omax, and PVR between the two groups (P > 0.05). Both the HoLEP and ThuVEP groups showed low incidences of complications and remarkably improved IIEF-EF scores at 12 months postoperatively, but with no significant differences (both P > 0.05). However, in those with relatively normal erectile functions before operation, the mean IIEF-EF score was reduced from 22.8 +/- 2.2 preoperatively to 21.0 +/- 2.7 after HoLEP, (P = 0.036).
CONCLUSIONBoth HoLEP and 120W ThuVEP are effective and safe in the treatment of BPH. Compared with HoLEP, 120 W ThuVEP has even a higher laser efficiency. However, neither can significantly improve erectile function, and HoLEP may have a short-term negative impact on the relatively normal erectile function of the patient.

Korean Journal of Ophthalmology 2008;22(2):130-132
We report a case of recurrent occlusion of laser iridotomy (LI) sites after a Visian ICL (Implantable contact lens version 4, Staar Surgical AG, Nidau, Switzerland) implantation. A 45-year-old woman had bilateral ICL implantation after placement of two peripheral LI sites in each eye to prevent pupillary block. At one month after the operation, severe narrowing or occlusion of four LI sites occurred. After this, although she received four additional LIs at postoperative months 1, 6, 9 and 10 in both eyes, the narrowing or occlusion recurred. Mild chronic anterior chamber inflammation was observed intermittently throughout the follow-up period. We performed clear lens extraction in both eyes (at postoperative month 11 in the left eye and month 26 in the right eye) due to recurrent occlusion of the LI sites and excess trabecular meshwork pigment deposition presumably caused by the four repeated LIs. Recurrent obstruction of LI sites can occur after ICL implantation. These problems were unresolvable despite four repeated laser iridotomies. The risks associated with anterior uveitis must be considered when planning an ICL implantation.
