ABSTRACT

Traumatic lesions of male external genitalia are certainly less frequent than the other body sites and in the majority of cases they are caused by work accidents in the metalworking environment or by gunshot wounds. We present a rare case of traumatic degloving lesion of the male external genitalia with avulsion of the left testis caused by an accidental fall from the ladder. Reconstructive surgery was carried out in a single procedure, obtaining an excellent esthetic and functional result.

ABSTRACT

BACKGROUND: Zoon balanitis (ZB) is a chronic inflammatory benign mucositis. Its etiopathogenesis still remains hypothetical and speculative. OBJECTIVES: To determine risk factors associated with genital ZB in men. METHODS: This is a case-control study including 30 patients diagnosed with ZB and 54 patients with dermatological diseases other than ZB enrolled in the Dermatological Clinic of the University of Padova, Italy, from September 2015 to June 2018. Univariate and multivariate logistic regression analyses were used for analysis of data collected. RESULTS: According to multivariate logistic regression analysis, risk factors for ZB were as follows: the mean daily cigarettes consumption (OR 1.065; 95% CI 1.8-11.4; P = 0.006) and the number of weekly foreskin retractions (OR 0.847; 95% CI 5.5-24.1; P = 0.003). There were no statistically significant differences between cases and controls according to age, presence of circumcision as well in number of sexual partners. CONCLUSIONS: To our knowledge, this is the first case-control study showing that smoking and poor genital hygiene are associated with being affected by ZB.

ABSTRACT

PURPOSE: The current literature on the impact of different urinary diversions on patients' health related quality of life (HR-QoL) showed a marginally better quality of life scores of orthotopic neobladder (ONB) compared to ileal conduit (IC). The aim of this study was to update the review of all relevant published studies on the comparison between ONB and IC. MATERIALS AND METHODS: Studies were identified by searching multiple literature databases, including MEDLINE, CINAHL, the Cochrane Library, PubMed Data were synthesized using meta-analytic methods conformed to the PRISMA statement. RESULTS: The current meta-analysis was based on 18 papers that reported a HR-QoL comparison between IC and ONB using at least a validate questionnaire. Pooled effect sizes of combined QoL outcomes for IC versus ONB showed a slight, but not significant, better QoL in patients with ONB (Hedges' g = 0.150; p = 0.066). Patients with ileal ONB showed a significant better QoL than those with IC (Hedges' g = 0.278; p = 0.000); in case series with more than 65% males, ONB group showed a slight significant better QoL than IC (Hedges' g = 0.190; p = 0.024). Pooled effects sizes of all EORTC-QLQ-C30 aspects showed a significant better QoL in patients with ONB (Hedges' g = 0.400; p = 0.0000). CONCLUSIONS: This meta-analysis of not-randomized comparative studies on the impact of different types of urinary diversions on HR-QoL showed demonstrated a significant advantage of ileal ONB compared to IC in terms of HR-QoL.

ABSTRACT

Bone density diseases such as osteoporosis affect a significant number of people worldwide. Lanthanide ions are functional mimics of calcium ions, able to substitute for Ca2+ in the bone mineral component, hydroxyapatite (HAP). Bone undergoes a continuous remodelling cycle and lanthanides can affect this cycle, exerting a positive influence on bone mineral. We have been engaged in efforts to find new lanthanide containing complexes as active agents for treatment of these diseases and have identified two lead compounds, 3-hydroxy-1,2-dimethylpyridin-4(1H)-one (Hdpp) and a phosphinate-EDTA derivative, bis[[bis(carboxymethyl)amino]-methyl]phosphinate (H5XT). In this paper, we report in vivo data for the first time for the two lead compounds. The pharmacokinetics of La(dpp)3 suggest the complex is rapidly cleared from plasma. We demonstrate that La3+ accumulates in the bone following IV dose of either La(dpp)3 or La(XT) and we have investigated the influence of each chelating ligand on the incorporation of La3+ into HAP using ITC and HAP-binding studies.

ABSTRACT

BACKGROUND: Klinefelter syndrome (KS) (47,XXY) is the most common sex chromosomal disorder, and it is a frequent form of male hypogonadism and infertility. Although the majority of these patients are azoospermic, they might have severe oligozoospermia or residual single-residual foci with spermatogenesis in the testis. AIM: We report our experience on sperm retrieval in the ejaculate and testis, and evaluate the frequency of chromosome abnormalities in sperm of KS. SUBJECTS AND METHODS: Eighty-four 47,XXY KS were evaluated with seminal analysis, body hair distribution, reproductive hormones, ultrasonographic scanning of the testis and prostate, bilateral testicular sperm extraction (TESE), sperm or testicular cells sex chromosomes aneuploidies. RESULTS: Out of 84 patients, 7 (7/84; 8.3%) had sperm in the ejaculate. Out of the 77 azoospermic patients, 24 underwent TESE and 9 (9/24; 37.5%) had successful sperm recovery. The comparison of reproductive hormones, age and testicular volume did not show significant differences between patients with and without successful sperm recovery in semen or TESE . Patients without successful sperm recovery in semen analysis or TESE had signs of hypoandrogenism more evident than patients with successful sperm recovery. Patients with KS produced a higher number of sperm aneuploidy with respect to normozoospermic fertile controls and non-genetic severely oligozoospermic men. CONCLUSIONS: Men with KS are not always sterile. In some of these patients sperm can be found in semen or in the testis, but the proportion of sperm aneuploidy is high. Signs of hypoandrogenism seem to be associated with low sperm recovery rate.

ABSTRACT

OBJECTIVE: The efficacy and safety of using alpha(1)-adrenergic blockers for treating primary bladder neck obstruction in young and middle-aged men was assessed as the first therapeutic step, before surgery, in a symptomatic non-neurogenic selected group of patients. MATERIALS AND METHODS: From January 1995 to December 2001, primary bladder neck obstruction was diagnosed in 41 men whose average age was 43 years. All of them were evaluated by a complete clinical history, American Urological Association (AUA) symptom score index, physical examination, uroflowmetry, transabdominal ultrasound prostatic volume determination, ultrasound post-void residual determination, videourodynamics including pressure-flow analysis and upper urinary tract screening with renal ultrasound or an excretory urogram. A full daily dose of alpha(1)-adrenergic blockers (alfuzosin or tamsulosin) was administered for at least 6 months. Successful treatment was defined as improved symptoms, voiding diary, maximum flow rate and pressure-flow parameters. Patients who did not gain improvement of symptoms with pharmacological treatment were offered surgery. RESULTS: Overall, pharmacological treatment was successful in 29/41 patients (70.7%) whereas bladder neck endoscopic incision was mandatory in 12/41 (29.3%). CONCLUSIONS: alpha(1)-Blockers were effective and safe for treating young and middle-aged men with symptomatic bladder neck obstruction.

ABSTRACT

Noninvasive (stages Ta, T1, Tis) transitional cell carcinomas of the upper urinary tract are suitable for a conservative therapeutic approach. Intracavitary therapy (alone or as adjuvant treatment) has recently been proposed and successfully used by some authors. Even though bacillus Calmette-Guérin is the most frequent agent employed, chemotherapeutic drugs, such as mitomycin C and thiotepa, have also been successfully used. The current information available in the literature is therefore reviewed. According to the data available, intracavitary therapy is a worthwhile conservative therapeutic option for noninvasive upper urinary tract urotheliomas with acceptable side effects. For this reason it may be included in the routine urological armamentarium.

ABSTRACT

PURPOSE: The appropriate treatment of superficial bladder neoplasm is still debated. The urologist must weigh the risk of tumor recurrence and progression against the possible side effects of conservative treatment (transurethral resection, intravesical therapy). Furthermore it is difficult to decide exactly when to abandon the conservative therapy and proceed with radical cystectomy and urinary diversion in order to prevent the potentially lethal sequelae of invasive bladder cancer. There are no certain scientific data on the appropriate therapeutic approach of recurrences of superficial bladder cancer after intravesical therapy and often the urologist takes a decision based on his personal experience ("art rather than science"). Based on these considerations, our aim was to evaluate applicable criteria to predict the risks of tumor recurrence and progression and so decide the best treatment for each patient. METHODS: 148 patients with multifocal, multirecurrent or persistent superficial bladder cancer (stage Ta-T1-Tis, G1-3) were treated with transurethral resection and/or two or more administration of intravesical chemo- (Mitomycin C, Doxorubicin, Epirubicin, Mitoxantron) or immuno-therapy (BCG) using common treatment schedule. Our first end point was the disease-free survival (DFS) evaluated by three different criteria: 1) "dynamic" stage (stage T1 diagnosed at the beginning, or during the follow-up or never); 2) "dynamic" grade (G3 tumor diagnosed at the beginning or during the follow-up or never); 3) "number of positive cystoscopies at the 3-year follow-up". Data were evaluated by a univariate statistical analysis (log-rank test) and a multivariate ones (MPLR stepwise procedure and L-ratio Cox's test). RESULTS: "Dynamic" stage: patients who never developed a T1 stage tumor have a better DFS than patients who developed a T1 stage tumor and even more than patients in which T1 was diagnosed from the beginning (p < 0.0001). "Dynamic" grade: patients who never developed a G3 tumor have a better DFS than patients who developed a G3 tumor and patients in which G3 tumor was diagnosed from the beginning (p < 0.0017). "Number of positive cystoscopies at the 3-year follow-up": patients with less than 3 positive cystoscopies have a better prognosis than patients with 3 or more positive cystoscopies at the three-year follow-up (p < 0.0380). DISCUSSION: We have found three independent predictive prognostic factors: "dynamic" stage, "dynamic" grade and number of positive cystoscopies at the 3-year follow-up. The statistical univariate and multivariate analyses allow us to define three risk categories for tumor progression (> or = T2): low, moderate, high.

ABSTRACT

PURPOSE: Endoscopic incision was performed as the initial therapy for ureteroceles in children presenting to our institutions between 1985 and 1990. To assess the long-term efficacy of this treatment modality we reevaluated the outcome of these patients. MATERIALS AND METHODS: Parameters reviewed included patient age at surgery, position of the ureterocele, a duplex system, preoperative and postoperative reflux, and the need for additional operations. Statistical analysis consisted of chi-square and Wilcoxon's rank sum tests. RESULTS: Of the patients 22 had intravesical and 22 had extravesical ureteroceles. Average age at initial surgery was 1.9 +/- 3.7 years with average followup of 7.2 +/- 3.1 years. A second operation was required in 18 cases (41%), which was significantly more likely for an extravesical ureterocele (18% versus 64%, p = 0. 002), a duplex system (p = 0.026) or preoperative reflux (p = 0.02). Second operations included reimplantation in 13 cases, upper pole partial nephrectomy in 7, total nephroureterectomy in 3, bladder neck reconstruction in 3 and lower pole pyeloplasty in 3. The only secondary operations performed for intravesical ureteroceles were reimplantation in 3 cases and upper pole nephrectomy in 1. New onset reflux developed in 14 of 27 patients (52%) postoperatively, including 7 with intravesical and 7 with extravesical ureteroceles. None required a second open operation. CONCLUSIONS: With extended followup the percentage of patients requiring open surgery after endoscopic incision of ureteroceles increased from our original report of 27% to 41% (p = 0.166). Only 18% of cases with an intravesical ureterocele required a subsequent operation compared to 64% with an extravesical ureterocele (p = 0.002). The reduction in size of the obstructed ureter following endoscopic decompression facilitated successful reimplantation. Endoscopic puncture permits definitive treatment in the majority of children by at most a single incision, open operation at the bladder level.
