ABSTRACT
Inflatable penile prosthesis (IPP) provides excellent outcomes after virgin implants. However, few data on IPP after revision surgery are available. This study aimed at comparing the outcomes of IPP in patients undergoing primary or revision implant surgery. Patients who underwent revision implant surgery (Group 1) between 2013 and 2020 were identified. Overall, 20 patients (Group 1) could be matched with a contemporary matched pair cohort of surgery-naive patients (Group 2) in a 1:1 ratio. Patients in Group 2 had a significantly shorter operative time [median (IQR): 84 (65-97) vs. 65 (51-75) min; p = .01] and lower rate of overall complications (25% vs. 10%; p = .01). Of note, mean (SD) scores for the Quality of Life and Sexuality with Penile Prosthesis (QoLSPP) questionnaire demonstrated high satisfaction and IPP efficacy in both Groups 1 and 2: functional domain [3.9 (1.0) vs. 4.0 (1.2); p = .4], personal [3.9 (1.1) vs. 4.0 (1.1); p = .3], relational [3.8 (1.3) vs. 3.9 (1.1); p = .5] and social [3.9 (1.1) vs. 4.0 (1.2); p = .2]. These results suggest that in experienced hands, IPP offers high satisfaction to both patients and partners even in the setting of revision implant. However, it is mandatory to inform those patients about the increased risk of perioperative complications.

PURPOSE: To compare perioperative results, safety and efficacy profile in patients receiving inflatable penile prosthesis (IPP) via penoscrotal (PS) or minimally invasive infrapubic (MII) approach for erectile dysfunction. METHODS: A matched-pair analysis was performed including 42 patients undergoing IPP implantation via PS (n = 21) or MII (n = 21) between 2011 and 2016. Clinical and surgical data were prospectively collected. Patients' and partners' outcomes were assessed by the International Index of Erectile Function (IIEF), Erectile Dysfunction Inventory of Treatment Satisfaction (EDITS) and Quality of Life and Sexuality with Penile Prosthesis (QoLSPP) questionnaires. RESULTS: Mean (SD) operative time was 128 (40.6) min in group PS and 91 (43.0) min in group MII (p = 0.041). Complications occurred in 3/21 (14%) and 2/21 (10%) patients in groups PS and MII (p = 0.832). Overall, no differences were observed concerning the device utilisation (p = 0.275). However, in group MII 4/21 (19%) patients were able to resume sexual activity prior to 4 postoperative weeks, while in group PS no patient was (p = 0.012). Mean (SD) scores for questionnaires were similar between groups PS and MII: IIEF [20.9 (7.3) vs. 20.7 (4.8); p = 0.132], patient EDITS [76.0 (25.6) vs. 74.7 (20.8); p = 0.256] and partner EDITS [72.5 (29.1) vs. 73.1 (21.4); p = 0.114]. Similarly, QoLSPP showed comparable results among the groups PS and MII: functional domain [3.9 (1.4) vs. 4.0 (1.2); p = 0.390], personal [4.0 (1.2) vs. 4.1 (1.0); p = 0.512], relational [3.7 (1.5) vs. 3.9 (1.2); p = 0.462] and social [4.0 (1.2) vs. 3.9 (1.2); p = 0.766]. CONCLUSIONS: PS and MII demonstrated to be safe and efficient techniques, leading to high level of both patients and partners satisfaction. Additionally, the minimally invasive infrapubic approach showed a shorter operative time and a tendency for a faster return to sexual activity.

PURPOSE: To evaluate the diagnostic accuracy of unenhanced and quantitative contrast-enhanced ultrasonography (US) in the differential diagnosis of small nonpalpable testicular lesions. MATERIALS AND METHODS: The local review board approved the protocol, and all patients provided written informed consent. One hundred fifteen patients (median age, 34 years; age range, 14-61 years) with nonpalpable testicular lesions were consecutively enrolled between 2006 and 2012 and underwent unenhanced scrotal US, contrast-enhanced US, surgical enucleation, and at least 18 months of follow-up. Clinical and histologic features were recorded, and qualitative and quantitative analysis of contrast-enhanced US time-intensity curves were performed. Logistic regression analysis was performed to explore features of malignancy. Receiver operating characteristic ( ROC receiver operating characteristic ) curves were developed for cumulative unenhanced and contrast-enhanced US scores. RESULTS: All lesions were 1.5 cm or smaller. Forty-four of the 115 patients (38%) had malignant tumors, 42 had benign tumors (37%), and 29 (25%) had nonneoplastic lesions. The features at unenhanced US that enabled the best differentiation of tumors versus nonneoplastic lesions and benign versus malignant tumors were parenchymal microlithiasis (26 of 86 patients with tumors vs five of 29 patients with nonneoplastic lesions [P = .178]; four of 42 patients with benign lesions vs 22 of 44 patients with malignant tumors [P < .001]), irregular margins (26 of 86 patients with tumors vs three of 29 patients with nonneoplastic lesions [P < .001]; eight of 42 patients with benign lesions vs 18 of 44 patients with malignant tumors [P < .001]), and internal vascularization (70 of 86 patients with tumors vs seven of 29 patients with nonneoplastic lesions [P < .001]; 28 of 42 patients with benign lesions vs 42 of 44 patients with malignant tumors [P < .001]). For contrast-enhanced US, the rapidity of wash-in (34 of 44 patients vs 15 of 42 patients, P < .001) and washout (33 of 44 patients vs five of 42 patients, P < .001) were the parameters that best differentiated malignant from benign tumors, with a typical prolonged washout observed in Leydig cell tumors (12 of 21 patients, P < .001 when compared with seminomas). Overall, the combination of unenhanced and contrast-enhanced US achieved a high accuracy in the diagnosis of small testicular malignancies (area under the ROC receiver operating characteristic curve performance: 0.927; 95% confidence interval: 0.872, 0.981). CONCLUSION: Benign testicular tumors are frequent incidental findings. Quantitative scrotal contrast-enhanced US is a noninvasive diagnostic tool that could improve the differential diagnosis and individualized management of small testicular lesions.

BACKGROUND: The minimally invasive infrapubic approach (MIIA) for inflatable penile prosthesis (IPP) placement has shown favorable peri-operative safety and efficacy profile, but scarce data exist on long-term follow-up. OBJECTIVES: We investigated the safety and efficacy of IPP implantation via the MIIA after a minimum 5-year follow-up. MATERIALS AND METHODS: We identified data of implanted patients prospectively included in our institutional database. Complications and functional outcomes were assessed by using validated tools. Specifically, quality of life and patient satisfaction were evaluated by the Quality of Life and Sexuality with Penile Prosthesis (QoLSPP) questionnaire. Kaplan-Meier method was used to analyze IPP survival (defined as a working IPP). RESULTS: Overall, 67 patients implanted by MIIA with a median (IQR) age of 64 years (61-70) were included. The median (IQR) follow-up duration was 71 months (63-80). Fifteen (22%) patients experienced complications: minor (Clavien ≤2) events included changes in penile sensitivity (n = 1; 1.5%), orgasmic dysfunction (n = 1; 1.5%), pain (n = 5; 7%), urinary tract infection (n = 2; 3%), and chronic discomfort (n = 1; 1.5%); major (Clavien 3) complications were represented by mechanical failure (n = 3; 4.5%), IPP infection (n = 1; 1.5%), and cylinder protrusion (n = 1; 1.5%). The estimated IPP survival was 94% (95% CI, 91.4-96.6), 92.5% (95% CI, 89.7-95.3), and 92.5% (95% CI, 89.7-95.3) at 3, 5, and 7 years after implantation, respectively. In patients using the device at follow-up (n = 61; 91%), median (IQR) scores for QoLSPP domains demonstrated favorable functional outcomes and patient satisfaction: functional 21 (19-23), personal 16 (15-18), relational 14 (12-15), and social 12 (11-14). DISCUSSION AND CONCLUSION: This study represents the longest follow-up using validated tools to assess the outcomes of IPP implantation via MIIA so far. IPP placement via MIIA confirms to be safe and to offer high satisfaction to both patients and partners at mid-term evaluation.

BACKGROUND: Testicular ultrasound (US) is routinely employed in the evaluation of reproductive and sexual function. However, its use for characteristics other than testicular volume is hampered by a lack of information on the prognostic value of its findings, which to date have only been incorporated in a score proposed by Lenz et al in 1993. OBJECTIVES: We sought to explore whether testicular US examination can predict the quality of spermatogenesis and provide information on testicular endocrine function. MATERIALS AND METHODS: We retrospectively reviewed 6210 testicular US examinations, finally selecting examinations from 2230 unique men. The following variables were considered: bitesticular volume and testicular asymmetry, parenchymal echotexture, echogenicity and presence of microlithiasis, solid lesions and varicocoele. Concurrent fasting hormonal data were available for 1160 men, while 979 had a semen sample available from the same day as the US examination. RESULTS: We derived a new US score, termed TU score, that can predict both impaired spermatogenesis (AUC 0.73, sensitivity 72%, specificity 61%, P < .001) and hypogonadism (AUC 0.71, sensitivity 71%, specificity 53%, P < .001) more accurately than the Lenz's score. In a multivariate analysis, a reduced sperm composite index (defined as total spermatozoa × total motility × normal forms) was independently predicted by bitesticular volume and by inhomogeneous echotexture, while hypogonadism was independently predicted also by reduced echogenicity and presence of microlithiasis. DISCUSSION AND CONCLUSIONS: We describe the testicular US characteristics that are independently associated with impaired spermatogenesis and hypogonadism and propose the TU score as a simple screening method for use in subjects referred for testicular US.

Introducción. Se ha descripto previamente que la cirugía bariátrica (CB) podría producir pérdida de la masa ósea dadas por alteraciones en el metabolismo mineral óseo. Se realizó este estudio con el objetivo de describir el impacto de la CB en el metabolismo óseo de pacientes en nuestro centro. Materiales y métodos. Estudio retrospectivo en el período 6/2007-3/2016. Se analizaron pacientes con datos de metabolismo óseo que requirieron CB. Se analizaron parámetros de laboratorio previos a la cirugía y a los 18 meses posteriores. Resultados. Se incluyeron 56 pacientes, con una mediana de edad de 47 años en un rango entre 26 y 70. Del total de los pacientes, 50 fueron intervenidos por gastrectomía vertical en manga y 6 por bypass gástrico. A pesar de no haber resultado estadísticamente significativos, se observó un incremento de los valores de vitamina D previos a la cirugía en comparación con este valor 18 meses posteriores (22 ng/ml vs 37 ng/ml respectivamente; p=0.194). Discusión. Se constató deficiencia de vitamina D prequirúrgica que revirtió en el pos operatorio, probablemente debido a la pérdida de peso, con la consiguiente liberación de la vitamina D secuestrada en el tejido adiposo, y a menor esteatosis y por consiguiente mayor metabolización hepática. Consideramos que es necesaria la realización de un estudio prospectivo con evaluación de la densidad mineral ósea en esta población de pacientes.(AU)
