Ten years of intraoperative floppy iris syndrome in the era of α-blockers.

INTRODUCTION: The use of alpha-1 receptor antagonists in the treatment of benign prostatic hyperplasia (BPH) has created a problem in ophthalmic surgery, the so-called intraoperative floppy iris syndrome (IFIS). This consists of a billowing iris, insufficient pupillary dilation with progressive intraoperative miosis, and protrusion of iris tissue through the tunnel and side port incision that are made for access to the anterior chamber during surgery. IFIS presents particular difficulties in cataract surgery which is carried out through the pupil with manipulations in the immediate vicinity of the iris. The complications range from poor visibility of the operative field to iris damage with the surgical instruments and to rupture of the posterior capsule, with loss of lens material into the vitreous body. MATERIAL AND METHODS: A comprehensive literature review was performed using MEDLINE with MeSH terms and keywords 'benign prostatic hyperplasia', 'intraoperative floppy iris syndrome', 'adrenergic alpha-antagonist' and 'cataract surgery'. In addition, reference lists from identified publications were reviewed to identify reports and studies of interest from 2001 to 2017. RESULTS: The A total of 95% of experienced ophthalmologic surgeons reported that systematic treatment with tamsulosin represents a challenging surgical condition increasing the risk of complications. Alpha-blockers are commonly prescribed, with 1,079,505 packages of tamsulosin prescribed each month in 2014 in Austria. Dose modification may be one way to reduce the risk of IFIS. A lower incidence of IFIS was reported in patients on tamsulosin in Japan, but the recommended dosage was lower than that used in Europe and the US (0.2 mg vs. 0.4 mg). CONCLUSIONS: We showed that not all patients taking tamsulosin experience IFIS. Moreover, larger investigations with a prospective design are needed, including studies to monitor the pre- and post-therapeutic ophthalmologic changes under tamsulosin, as well as urodynamic improvements resulting from this therapy.

Combined effects of varicocele and cell phones on semen and hormonal parameters.

BACKGROUND: The objective of this study was to evaluate if there is a combined effect of varicocele and cell phone storage in trousers pockets on semen and hormonal parameters. METHODS: A retrospective analysis of 468 men attending an infertility clinic from 1993-2007 was performed. Varicoceles were determined by clinical examination and patients were questioned on cell phone usage and storage fashion. Semen samples were analyzed according to the World Health Organization (WHO) guidelines of 1999. Serum testosterone, luteinizing hormone (LH) and follicle stimulating hormone (FSH) were assessed. RESULTS: There was a significant effect of cell phone storage in trousers pockets and varicocele in multivariate analysis (both p < 0.001). Varicocele showed an effect on sperm concentration (p = 0.003), LH (p = 0.014) and testosterone (p = 0.003). Compared to grade 1, grade 2 varicoceles showed a difference in sperm concentration (p = 0.004). Regarding testosterone differences were shown for grade 3 versus grade 1 (p = 0.002) and grade 3 compared to grade 2 (p = 0.003). Cell phone storage in trousers pockets showed an influence on the percentage of normal sperm morphology and LH (both p < 0.001). Varicocele and cell phone storage in trousers pockets did not show a combined effect (p = 0.76). CONCLUSIONS: This analysis showed an inverse relation between sperm concentration and degree of varicocele, with lower concentrations in higher grade varicoceles. Testosterone was significantly higher in higher grade varicoceles, which could reflect a compensatory mechanism to the impaired testicular function. Cell phone storage in trousers pockets showed an effect on LH and sperm morphology. A combined effect of varicocele and cell phone storage in trousers pockets was not detected.

Synergistic effects of cigarette smoking and varicocele on semen parameters in 715 patients.

OBJECTIVE: To evaluate whether there is a synergistic effect of varicocele and smoking status on semen parameters. METHODS: A retrospective evaluation of 715 men attending an infertility clinic between 2001 and 2009 was carried out. The presence of a varicocele was determined by clinical examination and cigarette smoking habits were documented allowing patients to be divided into 4 groups: non-smokers (n = 369), mild smokers (n = 186, 1-10 cigarettes/day), moderate smokers (n = 129, 10-20 cigarettes/day) and heavy smokers (n = 31, over 20 cigarettes/day). Semen samples were harvested according to the World Health Organization (WHO) guidelines. Additionally, serum luteinizing hormone (LH), free testosterone and follicle stimulating hormone (FSH) levels were measured in all patients. Multivariate analysis of variance (MANOVA) was carried out and further corroborated with the non-parametric Kruskal-Wallis and Mann-Whitney U­tests. A p-value of <0.05 was considered statistically significant. RESULTS: The median patient age was 30.2 years. Overall there was a statistically significant negative effect of higher varicocele grade on sperm motility and concentration (p < 0.05) and a significant negative effect of smoking status on sperm morphology and motility (very progressive, p < 0.01) as well as a significant synergistic effect of varicocele and smoking status on motility (p = 0.03). In the group of patients smoking less than 10 cigarettes per day no significant synergistic effect on semen parameters could be proven compared to patients with varicocele who did not smoke. CONCLUSIONS: We could show a significant synergistic effect of smoking status (>10 cigarettes) in patients with varicocele on sperm morphology and motility. These findings could play an important role in counselling infertile patients presenting with varicocele and severe smoking to improve their semen quality parameters if they stop smoking. Past smoking history was not investigated.

The Long-Term Effect of Radical Prostatectomy on Erectile Function, Urinary Continence, and Lower Urinary Tract Symptoms: A Comparison to Age-Matched Healthy Controls.

Introduction. To analyze the impact of radical prostatectomy (RPE) on erectile function and lower urinary tract function in comparison to age-matched healthy men. Materials and Methods. Patients who underwent radical retropubic prostatectomy completed questionnaires containing the IIEF-5, the Bristol female LUTS questionnaire, and the International Prostate Symptom Score (IPSS). Results. Patients after RPE were included (n = 363). Age-matched healthy men (n = 363) were included. The mean IIEF-5 of patients aged 61-70 yrs after RPE was 10.4 ± 6.6 versus 18.8 ± 5.3 in the control cohort; the respective values for men aged 71-80 yrs after RPE were 7.2 ± 6.5 versus 13.6 ± 7.7 in the control cohort. Urinary incontinence after RPE was reported in 41.9% (61-70 years) and 37.7% (71-80) versus 7.5% and 15.1% in the control cohort. The mean IPSS of patients after RPE aged 61-70 yrs was 5.0 ± 4.4 versus 5.5 ± 4.9 in the control cohort; the respective values for men aged 71-80 yrs were 6.0 ± 4.9 versus 7.5 ± 5.7 in the healthy cohort. Conclusions. The negative effect of radical prostatectomy on erectile and urinary incontinence remains substantial. The physiologically declining erectile and lower urinary tract function with ageing reduces the difference between healthy men and those after surgery. Healthy men have a higher IPSS presumably due to the presence of bladder outlet obstruction.

Impact of gender on tumor stage and survival of upper urinary tract urothelial cancer : A population-based study.

BACKGROUND: The aim of this study was to analyze the impact of gender on tumor stage, overall and cancer-specific mortality of upper urinary tract urothelial cancer (UTUC) in a population-based, nationwide analysis. METHODS: All Austrian patients with UTUC diagnosed between 1983 and 2010 were included in this study. Overall mortality was estimated by the Kaplan-Meier method. Cancer-specific (UTUC) mortality was estimated by cumulative incidence with mortality due to other causes as a competing risk. The effect of age was adjusted in a descriptive as well as a statistical inferential way. RESULTS: This study included 2066 patients (men n = 1169, mean age 68.3 ±11.5 years, women n = 897, 72.6 ±10.4 years). Tumor stage distribution was as follows: pT1: men n = 411, women n = 268, pT2: men n = 263, women n = 187, pT3: men n = 382, women n = 328 and pT4: men n = 113, women n = 114. The male:female ratio continuously declined from 1.5 for pT1 tumors to 1.4 for pT2 tumors, 1.2 for pT3 tumors and 1.0 for pT4-tumors. In the entire cohort the 5­year cumulative overall mortality was 57 % for women versus 50 % for men (p = 0.0002). For pT1 (women 33 %, men 31 %) and pT2 stage tumors (women 45 %, men 45 %) the 5­year overall mortality was comparable between both sexes. In pT3 (women 68 %, men 62 %) and pT4 (women 95 %, men 87 %) tumors women had a higher overall mortality rate. The 5­year cancer-specific mortality (CSM) of the entire cohort was 12 % for women and 10 % for men (p = 0.067): pT1 women 5 % men 3 %, pT2 women 9 % men 10 %, pT3 women 14 % men 11 % and pT4 women 29 % men 27 %. CONCLUSIONS: In this population-based nationwide analysis, sex differences were notable for UTUC. Women tended to have more advanced tumor stages at diagnosis and a higher overall and cancer-specific mortality in advanced tumor stages.

Abiraterone for castration-resistant prostate cancer: adherence, survival and hospitalization : Analysis of a medical claims database.

OBJECTIVE: To analyze the drug adherence rates and overall survival for in patients treated with arbiraterone acetate (AA) for castration-resistant prostate cancer (CRPC). METHODS: The database of the largest insurance company in Austria (Wiener Gebietskrankenkasse) was analyzed. Data on all CRPC patients with at least one prescription of AA between November 2011 and December 2014 in the postchemotherapy setting were collated and compared to the Austrian death and hospital admission statistics. Drug adherence was estimated by the medication possession ratio (MPR). RESULTS: Data of 270 patients (mean age 73.5 ± 8.9 years) were analyzed. The mean duration of AA treatment was 9.8 months (range 1-38 months). The duration of AA treatment was as follows: 0-2 months 53 patients (19.6 %), 3-5 months 73 patients (28.1 %), 6-10 months 67 patients (24.8 %) and >10 months 97 patients (35.9 %). The median MPR was 100 % and in 241 (89.2 %) the MPR exceeded ≥80 %. The median overall survival (OS) was 11 months. Based on Kaplan-Meier analysis, the 6 month OS was 61 %, 12 month OS 43 %, 18 month OS 35 % and >24 month OS 24 %. The OS was strongly correlated to patient age and the duration of AA treatment. Of all 270 patients, only 19 (7 %) were not hospitalized during their remaining life span and 71 (26.2 %) spent more than 50% of their remaining life span in hospital care. CONCLUSION: The OS was shorter than in phase III trials and strongly correlated to patient age and the duration of AA treatment. The high mortality rate within the first 6 months of AA treatment in this real-life setting suggests a less stringent patient selection than in a phase III trial.

The effect of vasectomy on the sexual life of couples.

INTRODUCTION: There are several contraceptive methods to prevent pregnancy, reversible as well as nonreversible ones. The sexual satisfaction of couples is affected by many types of contraceptives used. AIM: The aim of this study was to evaluate prospectively the effect of vasectomy on the sexual life and satisfaction of couples. METHODS: Seventy-six couples took part in this evaluation and filled out respective questionnaires before and after vasectomy. All the questionnaires were evaluated statistically for differences in the respective sexual domain scores. MAIN OUTCOME MEASURES: Standardized questionnaires were used. The International Index of Erectile Function (IIEF) as well as postoperative pain score were completed by men. Female Sexual Function Index (FSFI) was completed by the female partner. For statistical analysis, the T-Square Test was used. RESULTS: The average age of couples, who chose the vasectomy procedure, was 37 years for women and 39 years for men. The contraception method most frequently used prior to the vasectomy was the birth control pill. For the male partner, the IIEF showed no significant change in the respective domains. Out of the 76 couples, 93% of the males and 96% of their female partners would recommend and do vasectomy again. The postoperative pain score was 3.5 on 0-10 scale, and there were no postoperative complications reported. The best improvement of the sexual function was noticed for the female partners. The FSFI showed a significant improvement in the domains desire (P < 0.05), arousal (P < 0.05), orgasm (P < 0.05), lubrication (P < 0.05), and satisfaction (P < 0.05). CONCLUSION: This is the first report to our very best knowledge that showed the positive impact of vasectomy on sexual satisfaction of couples. Vasectomy is a safe operation with minimal complication rates.

Grade IV renal trauma in a 17-year-old patient.

Renal trauma occurs in 1-5% of all trauma cases. The kidney is the most commonly injured genitourinary and abdominal organ. In this case we present a 17-year-old patient with a grade IV trauma of the left kidney with renal rupture, hematoma, and urinoma. He was referred to our hospital in hemodynamic stability; therefore, a conservative approach was chosen. One year after the accident the patient was free from symptoms, and the renal function was normal; CT-scan revealed neither hematoma nor urinoma. Since nothing is known on the long-term outcomes in patients with severe renal traumas, long-term follow up studies are highly recommended.

Large stone clearance in 2-year-old child with staghorn and calyceal stones using SWL monotherapy.

Treatment of pediatric urolithiasis requires a thorough metabolic and urological evaluation on an individual basis. The objective of our case report was to determine the efficiency and the role of shockwave lithotripsy (SWL) in the treatment of pediatric urolithiasis. In this case report we reported our own experience in the management of staghorn and calyceal stones in both kidneys with SWL. In our case, clearance of multiple staghorn stones and a calyceal stone was obtained without any complications after 7 sessions of SWL over 2 months.

Is treatment of hemorrhagic radiation cystitis with hyperbaric oxygen effective?

OBJECTIVE: We report our own experience with the use of hyperbaric oxygen (HBO) for the management of postradiation hemorrhagic cystitis. METHODS: We reviewed retrospectively 14 patients from 2001 to 2007 with different pelvic organ malignancies who developed radiation cystitis after irradiation. Patients received 100% oxygen in a hyperbaric chamber at a pressure of 2.5 atmospheres absolute, 60 min bottom time, once a day, 7 days a week for at least 1 month. In principle, 30 HBO treatments per course were performed. After every course of HBO treatments, therapeutic effect was evaluated. The mean duration of follow-up of all patients was 18 months (range: 1-6 years). RESULTS: Patients were divided into 2 groups, group 1 (treatment group, n = 10) and group 2 (without treatment, n = 4). The mean duration between the onset of hematuria and the beginning of HBO therapy was 8.9 months (range: 3-34). Group 2 did not receive HBO because they were not healthy enough. Only 2 patients (20%) of group 1 recovered from their hemorrhagic cystitis. Group 1 had a significantly lower cure rate of postirradiation hemorrhagic cystitis in comparison to group 2. CONCLUSIONS: Our experience with the use of HBO did not yield favorable results. Randomized well-controlled studies are needed.
