Safety and efficacy of percutaneous nephrolithotomy in the Galdakao - Modified Supine Valdivia position: A prospective analysis.

OBJECTIVE: Aim of the present study was to evaluate the safety and efficacy of Percutaneous Nephrolithotomy (PCNL) in the Galdakao- Modified Supine Valdivia (GMSV) position in order to predict operative time, stone-free rate and onset of complications taking into account comorbidity, stone-related parameters and anatomic upper urinary tract abnormalities. MATERIAL AND METHODS: A prospective evaluation of patients who underwent to PCNL in GMSV position for renal stones > 2 cm, from January 2009 to February 2015 was performed. According to the technique, upper urinary tract abnormalities, stone chemical and morphological characteristics, and patients' history were matched with operative outcome, in terms of stone-free, intervention time and incidence of perioperative complications. RESULTS: Seventy-two cases were collected; mean operative time was 105 minutes (DS 41): staghorn stones and the presence of comorbidity resulted statistically significant variables. The complication-rate resulted in line with data showed in literature: hyperpyrexia and hemorrhage were the more frequently complications found. The overall stone-free was reached in 48 patients (67%), and it was influenced by patients' anatomic abnormalities. CONCLUSIONS: In the treatment of renal stones, PCNL may be a safe and effective choice; nevertheless, patients' anatomic abnormalities or staghorn-stones may influence the outcomes. Thus, a prospective study with a larger population is needed to verify our outcomes.

Recent aspects of sunitinib therapy in patients with metastatic clear-cell renal cell carcinoma: a systematic review of the literature.

Sunitinib is an orally available inhibitor of multiple tyrosine-kinase receptors approved for the treatment of advanced clear-cell renal cell carcinoma (ccRCC), a disease which has habitually had a very poor patient survival rate. Although it has become the most widely used drug for this disease, it remains not completely clear the best treatment strategy with these agent. The aim of this review is to highlight the most recent and interesting aspects of the research on treatment of advanced ccRCC with sunitinib and eventually determine alternative treatment schedule to reduce the incidence of side effects; we also wanted to review recent biomarkers able to predict response to therapy and also to point out the mechanism of acquired resistance to this drug.

A conservative approach to perineal Fournier's gangrene.

Fournier's gangrene (FG) is a disease involving necrosis of perineum and external genitalia; in 95% of cases it is possible to diagnose the Fournier's gangrene just by physical examination. The clinical presentation of FG varies from an initial localized infection to large areas with necrotizing infection. The disease typically affect elderly men (6°-7° decade) with important systemic comorbidities; women are less frequently affected. Despite improvements in diagnosis and management, the mortality rate nowadays is between 20% and 43%. The severity and mortality of the disease is dependent upon the general condition of the patient at presentation and upon the rate of spread of the infection. Treatment involves a multidisciplinary approach: intensive systematic management, broad-spectrum antibiotic therapy, early surgical debridement (wide abscission of necrotic tissues and surgical drainage of peritoneum, scrotum, penis, and inguinal areas), hyperbaric oxygen therapy; surgery can eventually be repeated if necessary; reconstructive surgery has an important role in the final treatment of the disease. The technical difficulties frequently encountered and the inability to make a complete removal of the necrotizing tissues at the time of surgery in some cases has led to the application of combined techniques, in view of the enhancement effect of specific advanced medications, targeted antibiotic therapy and hyperbaric medicine. We have considered 6 patients affected by Fournier's gangrene treated at our institution; all the patients received treatment with the help of plastic surgeons of the same institution. After debridement, all the patients were treated with advanced specific dressings consisting of plates and strips made of calcium alginate, hydrogels and polyurethane and twodimensional cavity foams. Reconstructive surgery was necessary in one case. Hyperbaric oxygen therapy (HBO) has been performed in all cases. The multidisciplinary approach, the combined use of HBO therapy and the adoption of advanced specific dressings, have made possible the complete healing of the lesions in a shorter period, avoiding further surgery in 5 out of 6 patients.

Improvement of lower urinary tract symptoms and sexual activity after open simple prostatectomy: prospective analysis of 50 cases.

OBJECTIVES: To evaluate the improvement of Lower Urinary Tract Symptoms (LUTS) and Erectile Function (EF) evaluated before and after Open Simple Prostatectomy, focusing on which patients this procedure allows better outcomes in term of sexual activity. MATERIAL AND METHODS: 50 men with large size benign prostatic hyperplasia (BHP) greater than 80 gr were prospectively evaluated before and 6 months after Open Simple Prostatectomy (Freyer procedure) between October 2012 to September 2013. Patients had a pre-operative transrectal ultrasound (TRUS) for volume evaluation and filled pre and post operative questionnaires for International Prostate Symptom Score (IPSS) and International Index of Erectile Function (IIEF-5) score. RESULTS: Mean patients age was 71 years (D.S. 3,5), mean prostate volume results 103 ml (D.S. 23,7); regarding LUTS and EF, mean improvement of IPSS score was 15,3 (D.S. 4) and mean increase of IIEF-5 score was 3,4 (D.S.3). This study highlights a correlation between patients' age and increase of IIEF-5 score; no correlation with prostate size was found. CONCLUSION: According to the EAU Guidelines 2014, large size BPH (over 80-100 mL) with LUTS refractory to medical management continue to have open prostatectomy as the treatment of choice. In our experience we found not only an reduction of LUTS after the procedure but also an improvement of erectile function; this improvement was related with patient's age.

The impact of repeated prostate biopsies on sexual function and urinary symptoms in patients with diagnosis of Atypical Small Acinar Proliferation (ASAP): can ecoDoppler reduce side effects?

OBJECTIVES: To establish whether repeated trans-rectal ultrasound-guided Prostate Needle Biopsies (PNBx) performed in men with diagnosis of Small Acinar Atypical Proliferation (ASAP) predispose these subjects to Erectile Dysfunction (ED) and to evaluate if EcoColorDoppler (ECD) can help to reduce this side effect. MATERIALS AND METHODS: We performed a retrospective study regarding 190 men with diagnosis of ASAP detected between January 2001 and December 2011, who underwent to repeated prostate needle biopsies (PNBx). These patients were investigated about Erectile Function (EF) and Lower Urinary tract Symptoms (LUTS) using International Index of Erectile Function (IIEF-5) and International Prostate Symptom Score (IPSS) questionnaires before the first PNBx and 3 months after each other one. In particular, among the 89 men without ED before first PNBx, we compared IIEF-5 score between 64 patients who underwent to standard PNBx and 25 patients submitted to a PNBx done with in addition ECD ultrasound imaging. RESULTS: Mean patient age was 65 years (SD 7.7); mean follow-up was 3.2 years (SD 1.8) and the mean number of re-biopsies completed was 2 (SD 1.5). Among the 143 men considered, only 89 resulted with a normal EF (IIEF-5 score > 21): in this group incidence of ED (IIEF-5 score < 21) among patients who underwent to standard PNBx was 4/64 (6.25%) while in patients submitted to a PNBx with ECD was 1/25 (4%). A greater decrease of EF was observed in patients undergone to 3 or more biopsies; no relationship between IPSS score and re-PNBx was identified. CONCLUSION: Repeated PNBx done in patients with diagnosis of ASAP appear to get worse EF; number of biopsies seems to increase the risk of ED. Use of ECD in transrectal ultrasound- guided PNBx may have a role to avoid neurovascular bundles (NVBs) and preserve EF; anyway further studies are highly recommended to validate this hypothesis.

Biopsy follow-up in patients with isolated atypical small acinar proliferation (ASAP) in prostate biopsy.

The incidence of prostate cancer (PCA) was evaluated in 155 patients with isolated Atypical Small Acinar Proliferation (ASAP) found on initial prostate biopsy, after a medium-term follow-up (40 months) with at least one re-biopsy. Clinical and histological data were analysed. Cancer was detected in 81 of 155 (52.3%). The cancer detection rate was 71.6%, 91.3%, 97.5%, 100% at the 1st re-biopsy, 2nd, 3rd, and 4th rebiopsy respectively. At the uni- and multivariate analyses, prostate volume (≤ 30 cc), transition zone volume (≤ 10 cc), small core length at the initial biopsy (≤ 10 mm) and few number of cores at initial biopsy (≤ 8) are predictive of cancer. Furthermore, tumour characteristics on the whole surgical specimens was assessed in 30 men: 13 of 30 (43 %) had clinically relevant cancer (volume > 0.5 ml or/and Gleason score ≥ 7, or pT3). Most of relevant cancers were detected in the distal apex, anterior gland and midline. These anatomical sites could be under-sampled at the initial biopsy using the transrectal approach. Our data suggest that follow-up biopsy is recommended in all cases of isolated ASAP detected after biopsy using endfire transrectal probe. The re-biopsy strategy should increase the number of cores (or a saturation biopsy), focusing on area of ASAP in the initial biopsy, but also including the under-sampled areas (anterior gland, distal apex and midline) to detect clinically relevant cancers.

Comparison of tamsulosin vs tamsulosin/sildenafil effectiveness in the treatment of erectile dysfunction in patients affected by type III chronic prostatitis.

AIM: We evaluated the effectiveness of tamsulosin monotherapy versus tamsulosin plus sildenafil combination therapy on erectile dysfunction (ED) in young patients with type III chronic prostatitis and ED by using symptom score scales. MATERIALS AND METHODS: 44 male patients were divided into 2 groups: the first group (20 patients) was treated with tamsulosin 0,4 mg monotherapy and the second one 24 patients) was treated with tamsulosin 0,4 mg plus sildenafil 50 mg combination therapy. "International Prostate Symptom Score, "National Institute of Health Chronic Prostatitis Symptom Index" (NIH-CPSI) and "International Index of Erectile Function" (IIEF-5) were investigated in each group of patients, and scores calculated during the first medical examination. Both groups were treated with tamsulosin once daily for 60 days, while sildenafil 50 mg was given on demand (at least 2 times per week) for 60 days. During the second medical examination IPSS, NIH-CPSI and IIEF-5 scores were analyzed once more. Afterwards, the alterations of scores among medical examinations in each group and between both groups were statistically compared. RESULTS: The age average of the 44 cases included was 32.04 3.15 years. Both groups present a statistically significant decrease, between the first and the second medical examination, in IPSS, NIH-CPSI scores and statistically significant increase in IIEF-5 score. In addition, there is no statistically significant difference, in all scores, between mono and combination therapy. CONCLUSIONS: tamsulosin monotherapy, as well as a combination therapy (tamsulosin plus sildenafil) has an improving effect on symptoms and on ED in patients with type III prostatitis. In the near future alpha-blockers monotherapy could be used in the treatment of chronic prostatitis and ED cases instead of phosphodiesterase type 5 (PDE-5) inhibitors combination therapy.

Conservative approach for a giant prostatic hyperplasia of 1280 ml: a case report and literature review.

Benign Prostatic Hypertrophy (BPH) affects at least one-third of men over 60 years. A giant prostatic hyperplasia (GPH) is a prostate enlargement that exceeds 500 g. We present a case of a 72-year-old man with a GPH volume of 1280 ml, referred to our hospital for a worsening of the lower urinary tract symptoms (LUTS), bilateral loin pain and kidney failure. Although the patient had a negligible post-void residual urine, he had bilateral hydronephrosis. The patient was managed conservatory because of a high anesthesiologic risk but a bilateral percutaneous nephrostomy was placed soon due to kidney function worsening. The presence of serious comorbidities and the resolution of the loin pain and the renal failure, achieved first with the nephrostomy and then with periodic replacement of ureteral stents, along with an improvement of the LUTS obtained with medical therapy, have oriented us towards a conservative management of the patient.

Primary non leukemic myeloid sarcoma of the ureteral wall: a case report of a rare disease.

Myeloid sarcoma (MS) is an extramedullary tumor mass causing proliferation of mature or immature blast cells of one or more myeloid lineages. Involvement of the genitourinary tract is rare. We present a case of MS of the ureteral wall. A 74-year-old man was evaluated for left hydronephrosis and ipsilateral low back pain. A computed tomography scan showed a nodular formation in the pelvic ureter. Urinary cytology revealed cellular atypia, so ureteroscopy was performed showing a distal ureteral mass. The histological examination of the biopsy revealed to be malignant neoplasm. The patient underwent left laparoscopic nephroureterectomy with bladder cuff excision. Microscopic histological examination revealed a tumor compatible with MS. A postoperative positron emission tomography revealed residual hypercaptation of the bladder, pelvic muscle and iliac nodes, so the patient started chemotherapy. A multidisciplinary approach was required, taking into account the patient's age, the already poor renal function and the location of the neoplasm.

Transrectal ultrasound (TRUS) and TRUS-biopsy accuracy in potential candidates for PRIAS active surveillance protocol.

AIM: Evaluate the transrectal ultrasound (TRUS) and TRUS-guided Biopsy (TRUS-Bx) accuracy in patients with low risk prostate cancer (PCA) that were potential candidate for PRIAS active surveillance (AS) protocol but underwent to immediate radical prostatectomy (RP). METHODS: 616 men were extracted from our institutional RP database. We selected the patients who met PRIAS inclusion criteria. The primary outcome was to evaluate the positive predictive value (PPV) and the specificity of suspected lesions at TRUS. The secondary outcome was to evaluate the TRUS-Bx accuracy in term of pathological upstaging and pathological upgrading with respect of RP specimen pathology report. RESULTS: 147 men of 616 (23.8%) in our RP database met PRIAS criteria; in this group we found 66 suspected lesions at TRUS examination (66/147: PPV 44.8%). Prostate cancer was really present in the biopsy specimen in only 32/66 of suspected lesions; in 28/66 the suspect lesion at TRUS was in the same position of the index lesion at final pathology. TRUS/biopsy specificity was 48% and TRUS/surgical specimen specificity 39%. TRUS-Bx staging accuracy: upgrading between biopsy and RP was recorded in 57/147 (38%) whereas 30/147 (20%) were upstaged on final pathology up to N1. CONCLUSIONS: TRUS and TRUS-Bx are insufficient tools to detect the grade, the location and the extent of PCA. New emerging techniques, such as US-MRI fusion biopsy and 3D template-guided transperineal saturation biopsy are promising to minimize the risk of misclassification and therefore to better select the best option of treatment (radical treatments or focal therapies or active surveillance) in each patient with low risk prostate cancer.

Malakoplakia of the urinary bladder: A review of the literature.

OBJECTIVE: The aim of the study is to make a review of the literature about bladder malakoplakia. MATERIAL AND METHODS: We searched articles on the PUBMED web-literature database with the following keywords: "vesical malakoplakia" and "bladder malakoplakia". In the literature we found 254 articles. At final we have excluded 219 articles, including in our study only 35 articles. RESULTS: The overall average age found was 50.85 years. The average age of men was 43.22 years, while that of women was 53.37 years. 75% of the patient cases were women and 25% were men. Regarding comorbidities, in 5.55% of the cases were missing whereas 47.22% of the patients suffered from recurrent urinary tract infection (UTI) and 19.44% from immune system disorders. Urine culture was positive in 69.44% with E.coli being isolated in 92% of cases. Hydroureteronephrosis was present in 44.44% of the cases: left in 6.25% of cases, right in 18.75% and bilateral in 75%. The mean serum creatinine of patients with hydroureteronephrosis was 5.11 (1-21) mg/dl. The most frequent site of the lesion was the vesicoureteral junction (VUJ) (42.31%), followed by the trigone (38.46%). 30.56% of patients were treated with antibiotic and surgery (transurethral resection of bladder, partial or radical cystectomy), less frequent options were antibiotics alone and surgery alone. The recurrence rate was 15%. CONCLUSIONS: Malakoplakia is a disorder usually related to other affections, like UTI and immunodepression, and it seem to be caused by an abnormal macrophage function. In almost half of the described cases of isolated bladder malakoplakia, hydroureteronephrosis and renal failure were present.Treatment is not standardized, but both medical and surgical therapies are effective to avoid recurrence.

Italian experiences in the management of andrological patients at the time of Coronavirus pandemic.

The SARS-CoV-2 (Severe acute respiratory syndrome coronavirus 2) was first reported in December 2019, then its rapid spread around the world caused a global pandemic in March 2020 recording a high death rate. The epicenter of the victims moved from Asia to Europe and then to the United States. In this Pandemic, the different governance mechanisms adopted by local health regional authorities made the difference in terms of contagiousness and mortality together with a community strong solidarity. This document analyzes the andrological urgencies management in public hospitals and in private practice observed in Italy and in particular in the most affected Italian Regions: Emilia-Romagna and Marche.

Correlation Between Confocal Laser Endomicroscopy (Cellvizio®) and Histological Grading of Upper Tract Urothelial Carcinoma: A Step Forward for a Better Selection of Patients Suitable for Conservative Management.

BACKGROUND: Despite the recent growing interest in the conservative management of upper tract urothelial carcinoma (UTUC), the diagnostic process is still a challenge for the risk of tumor undergrading. Real-time confocal laser endomicroscopy (CLE) provides in vivo microscopic images of tissues using a low-energy laser light source. OBJECTIVE: To describe our initial experience with CLE for the real-time characterization of UTUC. DESIGN, SETTING, AND PARTICIPANTS: Fourteen flexible ureteroscopies (f-URS) were performed at our center with CLE for UTUC. Lesions were preoperatively identified at computed tomography-intravenous urography. Cellvizio system was used during f-URS to perform CLE on the targeted lesions. Biopsies were then performed. INTERVENTION: f-URS with CLE. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: Surgeon's CLE readings (low-grade/high-grade/carcinoma in situ [CIS]) were documented in the operation notes. A dedicated genitourinary pathologist-blinded to the surgeon reading-examined all specimens. A third person collected prospectively the CLE readings and the histopathological reports. Cohen's Kappa analysis was performed to test interobserver agreement. RESULTS AND LIMITATIONS: The mean diameter of tumors at computed tomography scan was 26mm (range, 5-50mm). In eight patients, CLE allowed to obtain images compatible with low-grade UTUC, in five patients with high-grade UTUC, and in one case with CIS. We found correspondence between the CLE images and the final histopathological results in seven out of seven cases of low-grade UTUC (100%), in five out of six cases of high-grade UTUC (83%), and in one out of one case of CIS (100%). Substantial agreement was found at interobserver agreement (k=0.64) between CLE and histological reading. No complications and/or limitations related to the use of CLE were recorded. CONCLUSIONS: CLE is a promising new technology in providing a reliable real-time histological characterization of UTUC lesions. Ideal targets might be UTUC patients potentially candidates for conservative management. PATIENT SUMMARY: We believe that a conservative treatment for low-grade upper tract urothelial carcinoma is an option that must be considered. The diagnostic process is still lacking of accurate tools. In this study, we find that confocal laser endomicroscopy, using the Cellvizio system, seems to help the clinician to have a real-time histological characterization of upper tract urothelial carcinoma lesions. This could better select patients for a conservative treatment.

[Association between trauma and cancer of the testis: the importance of self-palpation of the testis for the early detection: two case reports]. / Associazione trauma-cancro del testicolo: l'autopalpazione nella diagnosi precoce; due casi clinici.

INTRODUCTION: Cancer of the testis is not always early detected and recognised, both by the physician and by the patient: sometimes physicians do not make an accurate genitals exam while patients often underestimate this problem. CASE REPORTS: Case I: 42-year-old man accepted from another hospital's Emergency, because of pain and edema of the right testis after a recent trauma on the gonad. At US, evidence of increased volume of the right testis with a large intraparenchymal hematoma. The markers were higher than normal. We performed a right orchiecthomy. The pathologist noted the presence of a mixed cancer of the testis (95% embryonal, 5% seminoma). Case II: 49-year-old man with hematuria, accepted from Emergency. The abdominal US revealed the presence of a voluminous neoformation (diameter of 12 cm) of the right kidney with neoplastic thrombosis of the right kidney vein. At the general physical exam, we detected the presence of an increased right testis, that at the US appared to be suspicious for cancer. Tumor markers were normal with the exception of αFP. We performed right nephro-adrenalectomy, right orchiectomy and removal of local nodes. The definitive histological examination demonstrated the presence of a seminoma of the testis and papillary carcinoma of the kidney with node metastasis. DISCUSSION: Current studies showed an association between trauma and cancer of the testis, even if some authors did not find this association because they consider that patients with trauma undergo US and in that occasion cancer is incidentally detected. CONCLUSIONS: The association between trauma and cancer of the testis is controversial in current studies. Furthermore screening for the cancer of the testis does not seem to be useful, even if the self- and the physician's palpation of the testis seem to be very important because in these two cases they should allow the early detection of the condition, with a resulting better prognosis.

[Isolated hydatid cyst of the kidney]. / Fistola cutanea da cisti idatidea isolata del rene: case report.

BACKGROUND: A hydatid cyst is a parasitic disease caused by the tapeworm Echinococcus granulosus. Kidney involvement represents 4% of all cases, and is rare compared to that in the liver or lung, even more as an isolated site of infection. We present a case report of a woman with septic status, cutaneous fistula and a renal cystic mass revealed to be a solitary hydatid cyst of the kidney. METHODS: A 60-year-old woman was referred acutely by another hospital to our department because of septic fever, cutaneous lumbar fistula and a left kidney cystic mass of 10 x 8 cm. We suspected a renal abscess and the patient underwent immediate left nephrectomy. RESULTS: We performed an extraperitoneal nephrectomy with a lumbar access under the 12th rib with complete resection of the fistula. The histopathological examination revealed it to be a hydatid cyst involving 2/3 of the kidney. After surgery a medical therapy with albendazol was administrated for 6 months, and the patient did not have any other localization 24 months after surgery. CONCLUSIONS: An isolated renal hydatid cyst presenting as cutaneous fistula with a septic status is a very rare condition. A pre-surgical diagnosis is not always possible as in this case. The surgical therapy (nephron-sparing or radical) is the key of the success and a medical therapy after surgery is recommended to prevent other localizations of this parasitic disease.
