Conservative treatment of Peyronie's disease: a guide.

PURPOSE: To review the literature on the topic, to suggest a common line of treatment applicable across a wide community of specialists, and to contribute in maintaining the high level of interest in this disease. METHODS: A comprehensive and exhaustive review of the literature was performed, identifying hundreds of articles on the topic. RESULTS: Peyronie's disease is a condition that has been recognized, studied, and treated for centuries; despite this, if one excludes surgery in cases in which the deformity is stable, no clear treatment (or line of treatment) is available for complete relief of signs and symptoms. Treatment options were divided into local, oral, and injection therapy, and a wide variety of drugs, remedies, and options were identified. CONCLUSIONS: Low-intensity extracorporeal shock wave therapy, vacuum therapy, penile traction therapy, phosphodiesterase type 5 inhibitors, hyaluronic acid, and collagenase of Clostridium histolyticum may be recommended only in specific contexts. Further studies on individual options or potential combinations are required.

Transient ureteral obstruction after mini-percutaneous nephrolithotomy is associated with stone volume and location: results from a single-center, real-life study.

PURPOSE: To evaluate the rate of and predictors of ureteral obstruction after mini-percutaneous nephrolithotomy (mPCNL) for kidney stones. METHODS: We analyzed data from 263 consecutive patients who underwent mPCNL at a single tertiary referral academic between 01/2016 and 11/2022. Patient's demographics, stone characteristics, and operative data were collected. A nephrostomy tube was placed as the only exit strategy in each procedure. On postoperative day 2, an antegrade pyelography was performed to assess ureteral canalization. The nephrostomy tube was removed if ureteral canalization was successful. Descriptive statistics and logistic regression models were used to identify factors associated with a lack of ureteral canalization. RESULTS: Overall, median (IQR) age and stone volume were 56 (47-65) years and 1.7 (0.8-4.2) cm3, respectively. Of 263, 55 (20.9%) patients showed ureteral obstruction during pyelography. Patients without ureteral canalization had larger stone volume (p < 0.001), longer operative time (p < 0.01), and higher rate of stones in the renal pelvis (p < 0.01) than those with normal pyelography. Length of stay was longer (p < 0.01), and postoperative complications (p = 0.03) were more frequent in patients without ureteral canalization. Multivariable logistic regression analysis revealed that stone volume (OR 1.1, p = 0.02) and stone located in the renal pelvis (OR 2.2, p = 0.04) were independent predictors of transient ureteral obstruction, after accounting for operative time. CONCLUSION: One out of five patients showed transient ureteral obstruction after mPCNL. Patients with a higher stone burden and with stones in the renal pelvis are at higher risk of inadequate ureteral canalization. Internal drainage might be considered in these cases to avoid potential complications.

Vacuum-assisted mini-percutaneous nephrolithotomy is associated with lower rates of infectious complications compared to vacuum-cleaner procedure in patients at high risk for infections: a single-center experience.

PURPOSE: To evaluate the impact of vacuum-assisted mini-percutaneous nephrolithotomy (vamPCNL) vs. vacuum-cleaner mPCNL (vcmPCNL) on the rate of postoperative infectious complications in a cohort of patients with high risk factors for infections. METHODS: We retrospectively analysed data from 145 patients who underwent mPCNL between 01/2016 and 12/2022. Patient's demographics, stones characteristics and operative data were collected. vamPCNL and vcmPCNL were performed based on the surgeon's preference. High-risk patients were defied as having ≥ 2 predisposing factors for infections such as a history of previous urinary tract infections, positive urine culture before surgery, stone diameter ≥ 3 cm, diabetes mellitus and hydronephrosis. Complications were graded according to modified Clavien classification. Descriptive statistics and logistic regression models were used to identify factors associated with postoperative infectious complications. RESULTS: vamPCNL and vcmPCNL were performed in 94 (64.8%) and 51 (35.2%) cases, respectively. After surgery, infectious complications occurred in 43 (29.7%) participants. Patients who developed infectious complications had larger stone volume (p = 0.02) and higher rate of multiple stones (p = 0.01) than those who did not. Infectious complications occurred more frequently after vcmPCNL than vamPCNL (55.9% vs. 44.1%. p = 0.01) in high-risk patients. Longer operative time (p < 0.01) and length of stay (p < 0.01) were observed in cases with infectious complications. At multivariable logistic regression analysis, longer operative time (OR 1.1, p = 0.02) and vcmPCNL (OR 3.1, p = 0.03) procedures were independently associated with the risk of infectious complications post mPCNL, after accounting for stone volume. CONCLUSION: One out of three high-risk patients showed infectious complications after mPCNL. vamPCL and shorter operative time were independent protective factors for infections after surgery.

Prevalence and predictors of stone passage after double J stenting for symptomatic ureteral stones: a cross-sectional, real-life study.

PURPOSE: To evaluate the rate of and predictors of stone passage (SP) after urgent retrograde stenting for symptomatic ureteral stones. METHODS: We retrospectively analysed data from 249 consecutive patients presenting to the emergency department for symptomatic ureteral stones and treated with retrograde stenting. Demographic, clinical and laboratory characteristics were collected. Stones parameters were collected before stenting and SP was evaluated at 1 month with computerized tomography. Descriptive statistics and logistic regression models tested the association between predictors and SP. RESULTS: Overall, median (IQR) age and stone diameter were 56 (45-68) years and 7.1 (4.4-9.8) mm, respectively. Stones were located in the proximal, mid and distal ureter in 102 (41.0%), 48 (19.3%) and 99 (39.8%) cases. SP was observed in 65 (26.2%) individuals. Stone diameter (3.2 vs. 7.7 mm, p < 0.001) and stone density (416 vs. 741, p < 0.001) were lower and a higher rate of distal stones (76.9% vs. 26.7%, p < 0.001) was found in the SP group compared to that with persistent stones. Multivariable logistic regression analysis showed that distal ureteral stone location (OR 7.9, p < 0.01) and lower HU (OR 0.9, p < 0.01) were associated with SP, after accounting for stone volume. Patients with a distal stone of 500 HU had a 75% probability of SP. CONCLUSION: Stone passage occurred in 26% of patients with indwelling stent due to symptomatic ureteral stones. Lower stone density and distal stone location were independent predictors of stone passage. Patients with these criteria should be managed with follow-up imaging and stent removal instead of ureteroscopy.

Clinically Meaningful Improvements in Sperm DNA Fragmentation Severity in Infertile Men Treated with Superoxide Dismutase Supplementation: A Single-Center Experience.

Background. Antioxidants are commonly used for the treatment of idiopathic male infertility. Previous studies have shown that antioxidants are able to improve sperm quality, but little is known about their impact on sperm DNA fragmentation (SDF). Preliminary findings showed that superoxide-dismutase (SOD)-based antioxidant plus hydroxytyrosol and carnosol (FertiPlus® SOD) therapy was associated with SDF improvement in a small cohort of infertile men. Therefore, we aimed to assess rates of and predictors of semen parameters and SDF improvements in infertile men treated with FertiPlus® SOD therapy (SOD+) or with other antioxidants without SOD (SOD−) in the real-life setting. Methods. Data from 60 consecutive infertile men with baseline SDF ≥ 30% and treated with SOD+ or SOD− for at least three months were analyzed. Clinical parameters and serum hormones were collected. Sperm parameters and SDF were requested at baseline and after SOD+ or SOD− treatment. Clinically meaningful SDF change after treatment was defined as SDF improvement >20% compared to baseline. Propensity score matching was performed to adjust for baseline differences between groups. Descriptive statistics were used to compare clinical and hormonal characteristics between SOD+ and SOD− groups. Semen characteristics were compared before and after treatment. Logistic regression models investigated the association between clinical variables and SDF improvement. Results. Groups were similar in terms of clinical, serum hormones and semen parameters at baseline after matching. Compared to baseline, sperm progressive motility (17 (10−36)% vs. 27 (12−41)%) and normal morphology (2 (1−6)% vs. 4 (2−6)%) significantly improved after SOD+ treatment (all p < 0.01), but not after SOD−. SDF values significantly improved after treatment in both groups, compared to the baseline evaluation (all p < 0.01). However, SDF values were lower after SOD+ than SOD− treatment (30 (22−36)% vs. 37 (31−42)%, p = 0.01). Similarly, a clinically meaningful improvement in SDF at follow-up was more frequently found after SOD+ than SOD− treatment (76.7% vs. 20.0%, p = 0.001). Multivariable logistic regression analysis showed that SOD+ treatment (OR 5.4, p < 0.001) was an independent predictor of clinically meaningful SDF improvement, after accounting for age and baseline FSH values. Conclusions. This cross-sectional study showed that, in a cohort of primary infertile men with SDF ≥ 30%, SOD-based treatment was significantly effective in improving SDF compared to antioxidants without SOD. Approximately 80% of men treated with SOD+ achieved clinically meaningful improvement in SDF after three months of treatment. Sperm progressive motility and normal morphology also improved after SOD+ therapy but not after SOD−. These results suggest that SOD+ treatment could be considered an effective option for the management of idiopathic infertile men with elevated SDF.

Coenzyme Q10 and Melatonin for the Treatment of Male Infertility: A Narrative Review.

BACKGROUND: Lifestyle and environmental factors can negatively impact fertility by means of oxidative stress. In this context, antioxidant supplementation therapy has gained much interest in recent years, and different molecules, alone or in combination, have been studied. OBJECTIVE: The purpose of the present review is to investigate the evidence regarding the efficacy of coenzyme Q10 (CoQ10) and melatonin on male infertility. METHODS: A literature search using PUBMED database from 2000 to October 2022 was performed to explore the role of CoQ10 and melatonin on male reproductive function. CONCLUSIONS: The analysis involved a narrative synthesis. CoQ10, alone or in combination, appears to reduce testicular oxidative stress and sperm DNA fragmentation and to improve sperm parameters; particularly sperm motility. Moreover, CoQ10 treatment is associated with higher pregnancy rates, both naturally and through assisted reproductive technology (ART). Larger studies are needed to precisely determine its clinical efficacy. Melatonin is a known antioxidant and preclinical studies have shown its ability to modulate reproductive function through hormonal and immune system regulation and sperm cell proliferation. Regardless, clinical studies are necessary to assess its potential in male infertility.

Varicocoele embolization with sclerosing agents leads to lower radiation exposure and procedural costs than coils: Data from a real-life before and after study.

OBJECTIVES: To investigate clinical outcomes, radiation exposure and procedural costs associated with percutaneous varicocoele embolization using coils and sclerosing agents (SAs) in a cohort of young-adult men. MATERIALS AND METHODS: Data from consecutive men treated with percutaneous varicocoele embolization using coils and SA between 2017 and 2021 were analyzed. The allocation was based on a change of policy occurred in June 2020 with the substitution of coils with SA (before and after study). Semen analysis values were based on 2010 WHO reference criteria. Anatomic variants of gonadal veins were categorized according to Jargiello et al. Intraoperative radiation dose and procedural costs were collected for each patient. Descriptive statistics and linear regression models were used to describe the association between clinical parameters with procedural costs and radiation exposure. RESULTS: One hundred sixteen men were included, of whom 76 (65.5%) received coils, and 40 (34.5%) received SA. Baseline characteristics of the two study groups did not differ. A type 3 Jargiello anatomic variation of left gonadal vein was found in 45.7% of cases. Radiation dose was lower in the SA group as compared to the coils one (13.2 [7-43] vs. 19.8 [12-57] Gy/cm2 ; p < 0.001). Similarly, procedural costs were lower for the SA group (169.6 [169-199] € vs. 642.5 [561-775] €; p < 0.001). At follow-up, pain and sperm variables significantly improved in both groups (p < 0.01), without differences among the embolic materials. Linear regression model revealed that coils use was associated with higher radiation exposure (beta 8.8, p = 0.02) than SA after accounting for anatomic variation of gonadal vein, body mass index, and vascular access. CONCLUSIONS: SA and coils for varicocoele embolization are equally safe and effective. The use of SA was associated with lower radiation exposure and procedural costs than coils. These results should be considered in terms of public health cost and patient's safety.

Sexual and ejaculatory function after holmium laser enucleation of the prostate and bipolar transurethral enucleation of the prostate: a single-center experience.

Currently available surgical treatments for Lower Urinary Tract Symptoms (LUTS) due to Benign Prostatic Obstruction (BPO) are associated with an increased risk of sexual dysfunction. The aim of our study is to compare sexual and ejaculatory function after Holmium Laser Enucleation of the Prostate (HoLEP) and Bipolar Transurethral Enucleation of the Prostate (B-TUEP). We performed a retrospective analysis of data prospectively collected from 62 (44.9%) and 76 (55.1%) patients who underwent HoLEP and B-TUEP, respectively. Erectile function and ejaculation characteristics were assessed with the International Index of Erectile Function-Erectile Function (IIEF-EF) domain and the Male Sexual Health Questionnaire-Ejaculatory function (MSHQ-EJ) questionnaires. Our study recorded no change in erectile function and no significant difference in rates of preserved antegrade ejaculation after both surgeries. One month after surgery, rates of physical pain/discomfort and perceived decreased physical pleasure during ejaculation were higher in HoLEP than B-TUEP patients (all p < 0.03). Moreover, HoLEP patients were more bothered by their ejaculatory difficulties than B-TUEP men (p = 0.03). At 3- and 12-months follow-up, all ejaculation-related differences disappeared. In conclusion, both procedures are valid alternatives for BPO treatment as they offer comparable urinary and sexual outcomes in the long term. However, in the first month after surgery, HoLEP patients present with more ejaculatory difficulties.

Outcomes and predictive factors of successful salvage microdissection testicular sperm extraction (mTESE) after failed classic TESE: results from a multicenter cross-sectional study.

Microdissection testicular sperm extraction (mTESE) has been proposed as a salvage treatment option for men with a previously failed classic TESE (cTESE), but data are scarce. We aimed to assess the outcome of and potential predictors of successful salvage mTESE in a cohort of men previously submitted to unfruitful cTESE. Data from 61 men who underwent mTESE after a failed cTESE between 01/2014 and 10/2020, at 6 tertiary-referral centres in Italy were analysed. All men were investigated with semen analyses, testicular ultrasound, hormonal and genetic blood testing. Pathological diagnosis from TESE was collected in every man. Descriptive statistics and logistic regression models were used to investigate potential predictors of positive sperm retrieval (SR+) after salvage mTESE. Baseline serum Follicle-Stimulating hormone (FSH) and total testosterone levels were 17.2 (8.6-30.1) mUI/mL and 4.7 (3.5-6.4) ng/mL, respectively. Sertoli-cell-only syndrome (SCOS), maturation arrest (MA) and hypospermatogenesis were found in 24 (39.3%), 21 (34.4%) and 16 (26.2%) men after cTESE, respectively. At mTESE, SR+ was found in 30 (49.2%) men. Patients with a diagnosis of hypospermatogenesis had a higher rate of SR+ (12/16 (75%)) compared to MA (12/21 (57.1%)) and SCOS (6/24 (25%)) patients at mTESE (p < 0.01). No clinical and laboratory differences were observed between SR+ and SR- patients at mTESE. There were no significant complications after mTESE. At multivariable logistic regression analysis, only hypospermatogenesis (OR 9.5; p < 0.01) was independently associated with SR+ at mTESE, after accounting for age and FSH.In conclusion, salvage mTESE in NOA men with previous negative cTESE was safe and promoted SR+ in almost 50%. A baseline pathology of hypospermatogenesis at cTESE emerged as the only independent predictor of positive outcomes at salvage mTESE.

Bipolar Transurethral Enucleation of the Prostate: Is it a size-independent endoscopic treatment option for symptomatic benign prostatic hyperplasia?

BACKGROUND: Bipolar Transurethral Enucleation of the Prostate (B-TUEP) is recommended as a first-choice treatment for benign prostatic obstruction in prostates >80 ml. Differently, B-TUEP is only considered as an alternative option after TURP for smaller prostates (30-80 ml). The aim of our study is to assess the relation between prostate size and surgical outcomes after B-TUEP. METHODS: We performed a retrospective analysis of data collected from 172 patients submitted to B-TUEP. Patients were segregated according to tertiles of prostate volume (PV) (≤60 ml, 61-110 ml, >110 ml). For each group we evaluated enucleation efficacy (enucleated weight/enucleation time), complication rates, urinary and sexual function parameters. Functional and sexual parameters were compared between groups at baseline, 1 and 3 months follow up. Descriptive statistics and linear and logistic regression models tested the association between PV and postoperative complications/outcomes. RESULTS: Operative time and weight of enucleated adenomas increased along with prostate volumes (all p≤0.01). Enucleation efficacy was higher in men with PV >110 ml compared to other groups (p≤0.001). Length of hospital stay, catheterization time and rates of postoperative complications, such as transfusion and clot evacuation rates and bladder neck/urethral strictures, were comparable between groups. Urinary symptoms improved at 1-and 3-months in each group as compared to baseline evaluation (all p<0.01) but they did not differ according to PV. In each group maximum urinary flow and post-void residual volume significantly improved at 3 months compared to baseline (all p≤0.01), without differences according to PV. Sexual symptoms were similar between groups at each follow up assessment. At multivariable linear and logistic regression analysis, prostate volume was not associated with postoperative functional outcomes and complications. Conversely, patient's comorbid status and antiplatelet/anticoagulation use were independently associated with postoperative complications. CONCLUSION: According to our findings, B-TUEP should be considered a "size independent procedure" as it can provide symptom relief in men with prostates of all sizes with the same efficacy and safety profile.

Rates of hypogonadism forms in Klinefelter patients undergoing testicular sperm extraction: A multicenter cross-sectional study.

INTRODUCTION AND OBJECTIVES: Adult patients with Klinefelter syndrome (KS) may present with testicular volume loss and a decrease in circulating testosterone (T) levels. However, the actual rate of hypogonadism in adult KS men is unknown. We aimed to (a) assess the prevalence of different forms of hypogonadism in a cohort of KS patients with non-obstructive azoospermia (NOA); and (b) investigate potential preoperative predictor of positive sperm retrieval (SR) at surgery in the same cohort of men. METHODS: Complete data from 103 KS men with NOA who underwent testicular sperm extraction (TESE) between 2008 and 2019 at five centers were analyzed. Comorbidities were scored with the Charlson Comorbidity Index (CCI). Patients were categorized into four groups of hypogonadism as follows: eugonadism [normal total T (tT) (≥3.03 ng/mL) and normal luteinizing hormone (LH) (≤9.4 mUI/mL)], secondary hypogonadism [low tT (≤3.03 ng/mL) and low/normal LH (≤9.4 mUI/mL)], primary hypogonadism [low tT (≤3.03 ng/mL) and elevated LH (≥9.4 mUI/mL)], and compensated hypogonadism [normal tT (≥3.03 ng/mL) and elevated LH (≥9.4 mUI/mL)]. Descriptive statistics tested the association between clinical characteristics and laboratory values among the four groups. RESULTS: Median (IQR) patients age was 32 (24, 37) years. Baseline follicle-stimulating hormone and tT levels were 29.5 (19.9, 40.9) mUI/mL and 3.8 (2.5, 11.0) ng/mL, respectively. Eugonadism, primary hypogonadism, and compensated hypogonadism were found in 16 (15.6%), 34 (33.0%), and 53 (51.4%) men, respectively. No patients had secondary hypogonadism. Positive SR rate at TESE was 21.4% (22 patients); of 22, 15 (68.2%) patients underwent assisted reproductive technology and five (22.7%) ended in live birth children. Patients' age, BMI, CCI, FSH levels, and positive SR rates were comparable among hypogonadism groups. No preoperative parameters were associated with positive SR at logistic regressions analysis. CONCLUSIONS: Findings from this cross-sectional study showed that 15.6% of adult KS men have normal tT values at presentation in the real-life setting. Most KS patients presented with either compensated or primary hypogonadism. Sperm retrieval rates were not associated with different forms of hypogonadism.

Sperm retrieval rates in non-mosaic Klinefelter patients undergoing testicular sperm extraction: What expectations do we have in the real-life setting?

BACKGROUND: A recent meta-analysis (Human Reproduction Update 23, 2017 and 265) reported positive sperm retrieval rates (SRR) in 50% of patients with Klinefelter syndrome (KS) undergoing testicular sperm extraction (TESE). However, these results do not reflect the rates of SR that we observe in clinical practice. We assessed the rate and potential predictors of SR in Klinefelter patients in the real-life setting. MATERIALS AND METHODS: We reviewed clinical data of 103 KS men who underwent TESE between 08/2008 and 03/2019 at five tertiary referral Andrology centers. Patients underwent testis ultrasound, hormonal evaluation, and genetic testing. All patients were azoospermic based on the 2010 WHO reference criteria. Conventional TESE (cTESE) or microsurgical TESE (mTESE) was performed based on the surgeon's preference. We used descriptive statistics and logistic regression models to describe the whole cohort. RESULTS: Median (IQR) patient's age was 32 (24-37) years. Baseline serum FSH and total testosterone levels were 29.5 (19.9-40.9) mUI/mL and 3.8 (2.5-11.0) ng/mL, respectively. Conventional TESE and mTESE were performed in 38 (36.5%) and 65 (63.5%) men, respectively. The sperm retrieval rate was 21.4% (22/103 men). Fifteen patients used spermatozoa for ICSI and five ended in live birth children. Patients with positive SR were similar to those with a negative TESE in terms of clinical, hormonal, and procedural parameters (all P > .05). Logistic regression analyses confirmed the lack of association between clinical, hormonal, and procedural parameters with SR outcome. DISCUSSION: Given the conflicting results in the literature regarding SRR in KS, patients should be carefully counseled regarding TESE outcomes based on data from published literature and local results. CONCLUSIONS: In the real-life setting, we observed a lower SRR (21.4%) than that reported in meta-analyses in our cohort of KS patients. No associations between clinical, hormonal, and procedural variables with TESE success were found.

Clinical Comparison of Holmium Laser Enucleation of the Prostate and Bipolar Transurethral Enucleation of the Prostate in Patients Under Either Anticoagulation or Antiplatelet Therapy.

BACKGROUND: A significant number of patients who require surgery for benign prostatic hyperplasia are under either anticoagulation (AC) or antiplatelet (AP) therapy. OBJECTIVE: To assess the efficacy and morbidity of holmium laser enucleation of the prostate (HoLEP) and bipolar transurethral enucleation of the prostate (B-TUEP) in patients who required AC/AP therapy. DESIGN, SETTING, AND PARTICIPANTS: This study included 296 (67.6%) and 142 (32.4%) patients who underwent HoLEP and B-TUEP, respectively. The AC/AP group included patients whose AP therapy was not interrupted pre-, peri-, and/or postoperatively, and patients who underwent perioperative AC therapy bridging with low-molecular-weight heparin. INTERVENTION: HoLEP and B-TUEP. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: We tested the hypothesis that AC/AP therapy had a limited impact on the efficacy of HoLEP and B-TUEP. To adjust for potential baseline confounders, propensity-score matching was performed. Clinical characteristics were compared among groups using the Kruskal-Wallis or chi-square test. Logistic regression analyses tested the association between clinical variables and the odds of Clavien-Dindo ≥2 complications after surgery. RESULTS AND LIMITATIONS: Overall, 28 (9.5%) and 46 (15.5%) patients in the HoLEP group and 15 (10.5%) and 24 (16.9%) men in the B-TUEP group had AC and AP therapy, respectively (p=0.9). HoLEP patients under either AC or AP therapy deserved longer catheter maintenance and a longer hospital stay (HS) than those without AC/AP therapy (all p≤0.01). Operative time, rates of postoperative complications, and 2-mo International Prostate Symptoms Score (IPSS) were similar between patients with and without AC/CP. Among B-TUEP patients, HS was longer (p=0.03) and the rate of complications was higher (p<0.001) in patients under AC or AP therapy. Postoperative haemoglobin drop and 2-mo IPSS were similar among groups and surgical techniques. Limitations are the retrospective nature of the study, and the lack of long-term complications and functional outcomes. CONCLUSIONS: HoLEP and B-TUEP can safely be performed in patients deserving continuous AP/AC therapy with only a slight increase in HS and catheterisation time. PATIENT SUMMARY: We assessed the safety and efficacy of holmium laser enucleation of the prostate (HoLEP) and bipolar transurethral enucleation of the prostate (B-TUEP) in men under chronic anticoagulation/antiplatelet therapy. Both HoLEP and B-TUEP could safely be performed as minimally invasive treatment options in this subset of patients at a high risk of bleeding from benign prostatic hyperplasia surgery.

Segmental testicular infarction: Case series and brief literature review of a great mime.

Segmental testicular infarction is rare, and the etiology is mostly idiopathic. We report a case series of four young patients, one of them with metachronous bilateral disease, presenting with an acute scrotum and treated with a testis-sparing approach, if feasible, after a negative intraoperative biopsy. Etiology, differential diagnosis, and management are reviewed. To be aware of clinical and imaging features of this benign testicular pathology, it is crucial to avoid unnecessary orchiectomies to preserve vital testicular tissue left.

Spontaneous upper urinary tract rupture caused by ureteric stones: a prospective high-volume single centre observational study and proposed management / Rotura espontanea del tracto urinario superior causada por litiasis ureteral: Estudio prospectivo observacional en un único centro de alto volumen y propuesta de manejo

Objective: To evaluate incidence, clinical, radiological and laboratory features of spontaneous upper urinary tract rupture (s-UUTR) due to ureteric stones and discuss their management. Methods: Out of 1629 patients admitted to the Emergency Department (ED) for renal colic from January 2015 to December 2016 and studied by kidney US and contrast enhanced CT (CECT), 31 patients had a s-UUTR categorized in 3 stages: a) local spread, b) free fluid, c) urinoma. Presentation, therapeutic procedures and outcomes were registered. Results: S-UUTR is reported in 1.9% of renal colic. The stone was most commonly identified at the vesicoureteric junction (VUJ) (61.3%) and mean (standard deviation, SD) stone size was 5.71 mm (2.31). S-UUTR was most frequently located in a calyx (54.84%). 26 patients (83.87%) had a clinical presentation of a renal colic, 3 cases (9.68%) had an atypical presentation and 2 (6.45%) presented an acute abdomen. In 26 cases a J-J stent (83,87%) was placed, 3 patients underwent primary ureteroscopic lithotripsy (9.67%); in 1 patient (3.23%) a nephrostomy was inserted and in 1 case (3.23%) active surveillance was adopted. Cases who underwent sole urinary derivation were revaluated after 30 days: ureteroscopic lithotripsy was performed in 48.15% of the cases; extracorporeal shock wave lithotripsy in 3.7%; in 22.2% of cases a CT demonstrated the spontaneous expulsion of the stone. 7 patients were lost at follow-up. The patient undergoing an active surveillance spontaneously expelled the stone. Conclusions: S-UUTR is a rare radiological sign of a renal colic most commonly located in a calyceal fornix. A high incidence of s-UUTR is caused by small distal ureteral stones in which a spontaneous passage is reasonable. Clinical presentation usually does not arise the suspicion of s-UUTR. In our experience, most patients were actively treated with good results but a conservative approach can be offered in selected cases

Objetivo: Evaluar la incidencia, las características clínicas, radiológicas y de laboratorio de la rotura espontanea del tracto urinario superior (re-TUS) debido a litiasis ureterales y discutir su manejo. Métodos: De 1629 pacientes admitidos en el Departamento de Urgencias por cólico renal entre enero 2015 y diciembre 2016 estudiados con ecografía renal y TAC con contraste, 31 pacientes presentaron re-TUS categorizada en 3 estadios: a) difusión local, b) líquido libre y c) urinoma. Se registraron la presentación, los procedimientos terapéuticos y los resultados. Resultados: Se comunica la re-TUS en 1,9% de los cólicos renales. La localización más frecuente de la litiasis es la unión ureterovesical (61,3%) y el tamaño medio (DE) fue de 5,71 mm (2,31). La localización más frecuente de la re-TUS fue en un cáliz (54,84%). En 26 pacientes (83,87%) la presentación clínica fue cólico renal, 3 (9,68%) una presentación atípica y 2 (6,45%) abdomen agudo. En 26 casos (83,87%) se colocó un catéter doble J, 3 pacientes fueron sometidos a ureteroscopia y litotricia in situ (9,67%); en 1 paciente (3,23%) se insertó una nefrostomía y en otro (3,23%) se adoptó la vigilancia activa. Los casos con derivación urinaria fueron reevaluados a los 30 días: se realizó ureteroscopia con litotricia en 48,15%, litotricia extracorporea por ondas de choque (LEOC) en 3,7%; en el 22,2% de los pacientes la TAC demostró la expulsión espontánea de la litiasis. 7 pacientes se perdieron en el seguimiento. El paciente sometido a vigilancia activa expulsó la litiasis espontáneamente. Conclusiones: La re-TUS es un signo radiológico raro del cólico renal localizado con mayor frecuencia en un fornix calicial. Las litiasis pequeñas del uréter distal en las que una expulsión espontanea es razonable, causan una alta incidencia de re-TUS. La presentación clínica no levanta habitualmente la sospecha de re-TUS. En nuestra experiencia, la mayoría de los pacientes fueron tratados activamente con buenos resultados, aunque se puede ofrecer tratamiento conservador en casos seleccionados

Spontaneous upper urinary tract rupture caused by ureteric stones: A prospective high-volume single centre observational study and proposed management. / Rotura espontanea del tracto urinario superior causada por litiasis ureteral: Estudio prospectivo observacional en un único centro de alto volumen y propuesta de manejo.

OBJECTIVE: To evaluate incidence, clinical, radiological and laboratory features of spontaneous upper urinary tract rupture (s-UUTR) due to ureteric stones and discuss their management. METHODS: Out of 1629 patients admitted to the Emergency Department (ED) for renal colic from January 2015 to December 2016 and studied by kidney US and contrast enhanced CT (CECT), 31 patients had a s-UUTR categorized in 3 stages: a) local spread, b) free fluid, c) urinoma. Presentation, therapeutic procedures and outcomes were registered. RESULTS: S-UUTR is reported in 1.9% of renal colic. The stone was most commonly identified at the vesicoureteric junction (VUJ) (61.3%) and mean (standard deviation, SD) stone size was 5.71 mm (2.31). S-UUTR was most frequently located in a calyx (54.84%). 26 patients (83.87%) had a clinical presentation of a renal colic, 3 cases (9.68%) had an atypical presentation and 2 (6.45%) presented an acute abdomen. In 26 cases a J-J stent (83,87%) was placed, 3 patients underwent primary ureteroscopic lithotripsy (9.67%); in 1 patient (3.23%) a nephrostomy was inserted and in 1 case (3.23%) active surveillance was adopted. Cases who underwent sole urinary derivation were revaluated after 30 days: ureteroscopic lithotripsy was performed in 48.15% of the cases; extracorporeal shock wave lithotripsy in 3.7%; in 22.2% of cases a CT demonstrated the spontaneous expulsion of the stone. 7 patients were lost at follow-up. The patient undergoing an active surveillance spontaneously expelled the stone. CONCLUSIONS: S-UUTR is a rare radiological sign of a renal colic most commonly located in a calyceal fornix. A high incidence of s-UUTR is caused by small distal ureteral stones in which a spontaneous passage is reasonable. Clinical presentation usually does not arise the suspicion of s-UUTR. In our experience, most patients were actively treated with good results but a conservative approach can be offered in selected cases.

Medical Expulsive Therapy for Symptomatic Distal Ureter Stones: Is the Combination of Bromelain and Tamsulosin More Effective than Tamsulosin Alone? Preliminary Results of a Single-Center Study.

OBJECTIVES: To assess the safety and efficacy of bromelain plus tamsulosin versus tamsulosin alone as medical expulsive therapy (MET) for promoting spontaneous stone passage (SSP) of symptomatic distal ureter stones. PATIENTS AND METHODS: One-hundred-fourteen patients with a 4-10 mm distal ureteral stone were enrolled (Group A). Patients self-administered daily bromelain with tamsulosin for 30 days or until SSP or intervention was mandatory. Patients were compared to those from a control group taking tamsulosin as MET (Group B) and matched for the following factors: sex, age ±10%, stone diameter. A logistic regression model evaluated bromelain and the ureteral stone diameter as explanatory variables. RESULTS: SSP rates were 87.7 vs. 75.4% for group A vs. group B respectively (p = 0.016); with no difference observed for the time to self-reported stone expulsion (11.68 vs. 11.57 days; p = 0.91). Considering larger stones (> 5 mm), the SSP rate was 83.3% in group A and 61% in group B (p < 0.01). With each millimeter increment of stone diameter, the probability of SSP decreased by 59.1% (p < 0.0001), while it increased of 3.3 when bromelain was present. Only 3 cases of tamsulosin-related adverse events were recorded. CONCLUSION: The association of bromelain and tamsulosin as MET increases the probability of SSP of symptomatic distal ureteral stones, with no bromelain-related side effects recorded.

Clinical comparison between conventional and microdissection testicular sperm extraction for non-obstructive azoospermia: Understanding which treatment works for which patient.

OBJECTIVES: The superiority of microdissection testicular sperm extraction (mTESE) over conventional TESE (cTESE) for men with non-obstructive azoospermia (NOA) is debated. We aimed to compare the sperm retrieval rate (SRR) of mTESE to cTESE and to identify candidates who would most benefit from mTESE in a cohort of Caucasian-European men with primary couple's infertility. MATERIAL AND METHODS: Data from 49 mTESE and 96 cTESE patients were analysed. We collected demographic and clinical data, serum levels of LH, FSH and total testosterone. Patients with abnormal karyotyping were excluded from analysis. Age was categorized according to the median value of 35 years. FSH values were dichotomized according to multiples of the normal range (N) (N and 1.5 N: 1-18 mIU/mL, and > 18 mIU/mL). Testicular histology was recorded for each patient. Descriptive statistics and logistic regression analyses tested the impact of potential predictors on positive SRR in both groups. RESULTS: No differences were found between groups in terms of clinical and hormonal parameters with the exception of FSH values that were higher in mTESE patients (p = 0.004). SRR were comparable between mTESE and cTESE (49.0% vs. 41.7%, p = 0.40). SRRs were significantly higher after mTESE in patients with Sertoli cell-only syndrome (SCOS) (p = 0.038), in those older than 35 years (p = 0.03) and with FSH >1.5N (p < 0.001), as compared to men submitted to cTESE. Multivariable logistic regression analysis showed that mTESE was independent predictor of positive SR in patients older than 35 years (p = 0.002) and with FSH > 1.5N (p = 0.018). Moreover, increased FSH levels (p = 0.03) and both SCOS (p = 0.01) and MA histology (p = 0.04) were independent predictors of SRR failure. CONCLUSIONS: Microdissection and cTESE showed comparable success rates in our cohort of patients with NOA. mTESE seems beneficial for patients older than 35 years, with high FSH values, or when SCOS can be predicted. Given the high costs associated with the mTESE approach, the identification of candidates most likely to benefit from this procedure is a major clinical need.
