Phytotherapy Might Have a Role in Reducing Unnecessary Prostate Biopsies: Results from an Exploratory, Randomized Controlled Trial of Two Different Phytotherapeutic Agents.

BACKGROUND: We aimed to evaluate the impact of two different phytotherapeutic agents on decision making regarding prostate biopsy for patients with higher-than-normal prostate-specific antigen (PSA) levels. METHODS: From June 2022 to May 2023, all patients attending two urological institutions due to higher-than-normal PSA levels were randomized to receive either oral capsules of Curcuma Longa, Boswellia, Pinus pinaster and Urtica dioica (Group A) or Serenoa Repens 320 mg (Group B) for 3 months. At the follow-up visit after 3 months, all patients underwent PSA tests and multiparametric magnetic resonance imaging (mpMRI). RESULTS: In the per-protocol analysis, data from 66 patients in Group A and 76 in Group B were analyzed. Fifty patients in Group A (75.7%) showed a significant reduction in total PSA compared to forty-nine in Group B (64.4%) (p < 0.001). Twenty-eight patients had PI-RADS III or higher in mpMRI: twelve in Group A and fourteen in Group B. Twenty-three patients (34.8%) in Group A and fifty-nine (77.6%) in Group B (p < 0.001) underwent prostate biopsy based on the mpMRI findings and PSA values. Three patients in Group A showed a significant reduction in total PSA values while having positive mpMRI findings (6%) compared with nine in Group B (19.5%) (p < 0.001). On the contrary, 7 patients in Group A did not show significant reduction in total PSA values and had negative mpMRI findings (43%) compared to 22 in Group B (81.4%) (p < 0.001). CONCLUSIONS: In conclusion, a three-month course of a combination of Curcuma Longa, Boswellia, Pinus pinaster and Urtica dioica seems to be an interesting tool to avoid unnecessary prostate biopsies among men with higher-than-normal PSA levels.

Is a Drain Needed After Robotic Radical Prostatectomy With or Without Pelvic Lymph Node Dissection? Results of a Single-Center Randomized Clinical Trial.

Objective: To investigate by means of a randomized clinical trial the safety of no drain in the pelvic cavity after robot-assisted radical prostatectomy (RARP) with or without extended pelvic lymph node dissection (ePLND). Materials and Methods: From May to December 2016, 112 consecutive patients who underwent RARP with or without ePLND were prospectively randomized into a control group (CG) and study group (SG). In the CG, a drain was placed in the pelvic cavity at the end of surgery and removed after 24 hours. The trial was designed to assess noninferiority. The primary endpoint was evaluated as complication rates graded by the Clavien-Dindo score (CDS). Secondary endpoints included length of hospital stay (LOHS) and hospital readmission (RAD). Results and Limitations: At final analysis, 56 patients were in the CG and 54 belonged to the SG. The groups were homogenous for all preoperative and perioperative variables and did not show any difference in CDS complication rates (28.9% in the CG and 20.4% in the SG; p = 0.254), LOHS (on average 4 days in each group; p = 0.689), and RAD rates (3.6% in the CG and 3.7% in the SG; p = 0.970). Conclusions: In a modern cohort of patients who underwent RARP with or without ePLND, a single-center randomized controlled trial showed that no-drain policy is equivalent to drain after RARP in terms of CDS complication rate, LOHS, and RAD rate. The option of placing a postoperative drain for the first 24 hours could be considered in cases of difficult urethrovesical anastomosis with uncertain watertightness.

Robotic bladder diverticulectomy: step-by-step extravesical posterior approach - technique and outcomes.

OBJECTIVE: The aim of this study was to evaluate the feasibility of robotic extravesical posterior surgical bladder diverticulectomy for treatment of symptomatic bladder diverticula (BD). MATERIALS AND METHODS: Data from patients with posterior BD who consecutively underwent robotic bladder diverticulectomy (RBD) from 2013 to 2016 in Azienda Ospedaliera Universitaria Integrata, Verona, were retrospectively reviewed. Baseline characteristics, perioperative outcomes including operative time (OT), estimated blood loss (EBL), postoperative transfusion rate and length of hospital stay (LOS), and early (30 days) and late (90 days) postoperative complications were recorded and analysed. RESULTS: Six patients underwent RBD. Storage, voiding and postvoiding lower urinary tract symptoms (LUTS) were reported by 33.3%, 100% and 33.3% of patients, respectively. The median [interquartile range (IQR)] BD diameter was 7.1 (5.5-9.5) cm; median (IQR) preoperative postvoiding residual volume (PVR) was 300 (90-395) ml. The median (IQR) OT was 112.5 (83.7-133.7) min and median (IQR) EBL was 25.8 (0-50) ml. The median (IQR) LOS was 7 (4.7-9.0) days. One patient (16.7%) reported early minor postoperative complication. No patient showed early or late major postoperative complications. At 2 month follow-up, all patients underwent a lower abdomen ultrasound and minimal or no postoperative PVR was found. At 6 month follow-up no LUTS were reported. CONCLUSIONS: RBD appears to be a safe treatment for posterior BD with excellent perioperative and functional outcomes. The three-dimensional visualization, greater magnification and wristed instrumentation with seven degrees of freedom allow precise dissection of BD and reconstruction of the bladder wall.

A rare complication of ureteral stenting: Case report of a uretero-arterial fistula and revision of the literature.

INTRODUCTION: Uretero-arterial fistulas are a rare condition. The most frequent clinical sign is hematuria. Since these bleedings occur intermittently, the diagnosis is very difficult. If not discovered, uretero-arterial fistulas involve a very high rate of mortality or even results in loss of kidney function. CASE REPORT: The clinical case we describe is an unusual one. After a radical hysterectomy and a subsequent radiotherapy, a hydronephrosis caused by ureteral fibrosis occurred on both sides. Therefore, the patient received bilateral ureteral stents. During a change of the ureteral stents 18 months later, a massive bleeding appeared in the right ureter. Initially, a clear evidence of a fistula was not possible - neither through CT scan nor through selective angiography. There were some indicators of a uretero-arterial fistula, so an endoluminal vessel stent was placed. Subsequently the fistula probably led to an erosion of the vessel stent. DISCUSSION: A fistula between the ureter and the iliac artery (UAF) is a rare complication. The increase in known cases during the last years is linked to the possibility of ureteral stenting since 1978. Until now only 140 cases have been described in literature. The mortality rate through UAF has decreased from 69% in 1980 to 7-23% today. Its development can be traced through the pulsation of the artery and the pressure on the ureter. The most important clinical symptom is bleeding. Diagnosis is generally difficult and represents the real problem. The sensitivity of the standard angiography examination is 23- 41%; it can be improved to 63% using the "provocative" method, which means mobilizing the ureteral stent during examination. The therapy in course of the angiography consists of a simultaneous endovascular stent and/or a co-embolisation. CONCLUSION: Arterial or uretero-arterial fistulas (UAF) are a rare condition; the diagnosis is very difficult and most of the time the treatment requires a multidisciplinary team.

Associations of Transitional Zone Volume with Intraprostatic Chronic Inflammation and Prostate Cancer Risk in Patients Undergoing a First Random Biopsy Set.

OBJECTIVES: To investigate associations of the transitional zone volume (TZV) with intraprostatic chronic inflammatory infiltrate (CII) and prostate cancer (PCa) risk in patients undergoing a first random biopsy set. MATERIALS AND METHODS: The study included a homogenous population of 596 patients. The volume of the prostate and TZV were separately measured. Independent associations were investigated by multivariate logistic regression analysis. RESULTS: The median TZV was 18 ml, CII was detected in 157 cases (26.3%), and PCa was present in 292 patients (49%). TZV was the only independent clinical factor associated with CII risk (OR = 1.014). After correcting for CII (OR = 0.276; p < 0.0001), independent factors associated with PCa risk included age (OR = 1.066), prostate specific antigen (OR = 1.177), TZV (OR = 0.919), and an abnormal digital rectal exam (OR = 2.024). CONCLUSION: In a patient population undergoing a first random prostate biopsy set because of suspected cancer, independent associations were detected among TZV, CII, and PCa. The association between TZV and CII was direct, but the relation between TZV and PCa was inverse. The measurement of the volume of the transitional zone was a useful parameter for evaluating chronic intraprostatic inflammation and PCa risk.

Acute Ischemia of the Glans Penis after Circumcision Treated with Hyperbaric Therapy and Pentoxifylline: Case Report and Revision of the Literature.

Acute severe ischemia of glans penis after circumcision is a very rare event and, if not treated, can lead to irreversible necrosis with severe consequences such as loss of part of the penis. The possible causes for this condition could be blood-vessel binding or cauterization, dorsal penile nerve block (DPNB), local anesthesia with vasoconstricting agents and wound dressing compression. The aim of the treatment is to provide good blood supply and thus, oxygen delivery to the ischemic penis. The therapeutic options include hyperbaric therapy (HBOT), pentoxifylline (PTX), enoxaparina, iloprost, antiplatelet, corticosteroids and peridural anesthesia. We report the case of a 24-year-old male who developed an acute severe glans penis ischemia after circumcision done under DPNB. The patient was successfully treated with HBOT in combination with PTX.

Low-Risk Prostate Cancer and Tumor Upgrading in the Surgical Specimen: Analysis of Clinical Factors Predicting Tumor Upgrading in a Contemporary Series of Patients Who were Evaluated According to the Modified Gleason Score Grading System.

OBJECTIVE: To identify significant clinical factors associated with prostate cancer (PCa) upgrading the low-risk PCa patients graded according to the modified Gleason score system. MATERIALS AND METHODS: The logistic regression model was used to evaluate the records of 438 patients. RESULTS: There were 170 cases (38.8%) of low-risk PCa and tumors were upgraded in 111 patients (65.3%). Only prostate specific antigen (PSA) and the proportion of positive cores (P+) were independent predictors of tumor upgrading. Further exploration was investigated by categorizing and regressing PSA (≤ 5.0 vs. > 5.0 ng/ml) and P+ (≤ 0.20 vs. > 0.20). The odds ratio of PSA > 5 ng/ml was 1.32 and of P+ > 0.20 was 2.71. The population was stratified into very low-risk with PSA ≤ 5 ng/ml and P+ ≤ 0.20 (class A), low-risk with PSA > 5 ng/ml and P+ ≤ 0.20 (class B), intermediate risk with PSA ≤ 5 ng/ml and P+ > 0.20 (class C), and high risk with PSA > 5 ng/ml and P+ 0.20 (class D). Upgrading rates were extremely low in class A (9%), extremely high in D (50.5%), and moderate (20%) in B and C. CONCLUSION: Patients diagnosed with low-risk PCa at biopsy are a heterogeneous population because they include subsets with undetected high-grade disease. Significant clinical predictors of upgrading include the PSA value and P+. In low-risk PCa, we identified a high-risk upgrading subgroup that needed repeat biopsies in order to reclassify the tumor grade and to reassess the clinical risk category.

Prostate volume index stratified prostate cancer risk in patients elected to a first random biopsy set.

OBJECTIVE: To investigate prostate volume index (PVI), defined as the ratio of volume of the transitional zone on that of the peripheral zone, as a factor stratifying prostate cancer (PCA) risk in patients elected to a first random biopsy set. METHODS: The study evaluated 596 patients who were elected to a first random biopsy set because of suspected PCA in a period between September 2010 and September 2015. Prostate volume index was dichotomized to PVI ≤1 vs PVI >1. The multivariate logistic regression model investigated clinical factors with dichotomized PVI associating with PCA. RESULTS: The detection rate of PCA was 49%. The dichotomized PVI >1 stratified PCA risk (odds ratio [OR] 0.455; p<0.0001) beyond age (OR 1.062; p<0.0001), PSA (OR 1.167; p<0.0001), PV (OR 0.957; p<0.0001), and abnormal digital rectal examination (OR 2.094; p<0.0001). The goodness of fit statistics assessed model efficacy. CONCLUSIONS: A large cohort of patients elected to a first random biopsy set had PCA risk stratified by dichotomized PVI beyond other clinical independent factors. Confirmatory studies are required.

Prostate Volume Index Associates with a Decreased Risk of Prostate Cancer: Results of a Large Cohort of Patients Elected to a First Biopsy Set.

Background/Aims/Objectives: In patients elected to the first prostate biopsy set, the risk of prostate cancer (PCA) may be predicted by clinical factors. The aim of this study was to investigate on prostate volume index (PVI), defined as the ratio of volume of the transitional zone to the volume of the peripheral zone, and PCA risk. METHODS: The study retrospectively evaluated 1,327 patients and included only the first biopsy set with 14 cores. PCA risk was assessed by using the multivariate logistic regression model. RESULTS: The analysis evaluated 596 patients. The detection rate of PCA was 49%. Age, prostate specific antigen, PVI and digital rectal exam were independent factors of PCA risk, which was decreased by PVI (OR 0.224; 95% CI 0.157-0.380). The goodness of fit statistics assessed model efficacy. CONCLUSIONS: In a large cohort undergoing the first biopsy set, PVI associated with a decreased risk of PCA. Confirmatory studies are required.

An unusual case of pneumatic nail gun scrotal injury and revision of the literature.

Pneumatic nail guns are hand-held tools commonly utilized in both industrial and non occupational setting. These devices facilitate production and boost efficiency but also can be a potential cause of serious injuries. Nail guns are the most frequent tool associated trauma with hospitalization among construction workers. The most common sites of injuries are the hand or fingers followed by the lower extremities. We report the first case in literature of a work nail gun injury to male external genitalia.

Chronic Inflammation in Prostate Biopsy Cores is an Independent Factor that Lowers the Risk of Prostate Cancer Detection and is Inversely Associated with the Number of Positive Cores in Patients Elected to a First Biopsy.

OBJECTIVES: To investigate associations of chronic inflammatory infiltrate (CII) with prostate cancer (PCa) risk and the number of positive cores in patients elected to a first set of biopsies. MATERIALS AND METHODS: Excluding criteria were as follows: active surveillance, prostate specific antigen (PSA) ≥ 30 ng/l, re-biopsies, incidental PCa, less than 14 cores, metastases, or 5-alpha reductase inhibitors. The cohort study was classified as negative (control group) and positive cores between 1 and 2 or > 2. RESULTS: The cohort included 421 cases who did not meet the exclusion criteria. PCa was detected in 192 cases (45.6%) of which the number of positive cores was between 1 and 2 in 77 (40.1%) cases. The median PSA was 6.05 ng/ml (range 0.3-29 ng/ml). Linear regression models showed that CII was an independent predictor inversely associated with the risk of PCa. Multinomial logistic regression models showed that CII was an independent factor that was inversely associated with PCa risk in cases with positive cores between 1 and 2 (OR = 0.338; p = 0.004) or more than 2 (OR = 0.076; p < 0.0001) when compared to the control group. CONCLUSION: In a cohort of men undergoing the first biopsy set after prostate assessment, the presence of CII in the biopsy core was an independent factor inversely associated with PCa risk as well as with the number of positive biopsy cores (tumor extension). Clinically, the detection of CII in negative biopsy cores might reduce the risk of PCa in repeat biopsies as well as the probability of detecting multiple positive cores.

Low-Risk Prostate Cancer and Tumor Upgrading to Higher Patterns in the Surgical Specimen. Analysis of Clinical Factors Predicting Tumor Upgrading to Higher Gleason Patterns in a Contemporary Series of Patients Who Have Been Evaluated According to the Modified Gleason Score Grading System.

OBJECTIVE: To identify clinical factors associated with prostate cancer (PCA) upgrading to higher patterns of the surgical specimen in low-risk PCA. MATERIALS AND METHODS: We evaluated the records of 438 patients. The multinomial logistic regression model was used. RESULTS: Low-risk PCA included 170 cases (38.8%) and tumor upgrading was detected in 111 patients (65.3%) of whom 72 (42.4%) had pathological Gleason patterns (pGP) = 3 + 4 and 39 (22.9%) pGP >3 + 4. Prostate-specific antigen (PSA) and proportion of positive cores (P+) were independent predictors of tumor upgrading to higher patterns. The main difference between upgraded cancers related to PSA and to P+ >0.20. The population was stratified into risk classes by PSA ≤5 µg/l and P+ ≤0.20 (class A), PSA >5 µg/l and P+ ≤0.20 (class B), PSA ≤5 µg/l and P+ >0.20 (class C) and PSA >5 µg/l and P+ 0.20 (class D). Upgrading rates to pGP >3 + 4 were extremely low in class A (5.1%), extremely high in D (53.8%). CONCLUSIONS: Low-risk PCA is a heterogeneous population with significant rates of undetected high-grade disease. Significant clinical predictors of upgrading to higher patterns include PSA and P+, which identify a very high-risk class that needs repeat biopsies in order to reclassify tumor grade.

Introduction of an enhanced recovery protocol to reduce short-term complications following radical cystectomy and intestinal urinary diversion with vescica ileale Padovana neobladder.

OBJECTIVES: To reduce short-term complications of radical cystectomy (RC) and intestinal urinary diversion with vescica ileale Padovana (VIP) neobladder, we described and assessed an enhanced recovery protocol (ERP) in a series of consecutive patients. METHODS: An ERP was introduced focusing on reduced bowel preparation, standardized feeding and analgesic regimens. We analyzed the outcomes with all patients consecutively undergoing RC and VIP neobladder who met the following inclusion criteria: American Society of Anesthesiologists score <3; absence of malnutrition according to the Mini Nutritional Assessment-Short Form criteria; absence of inflammatory bowel diseases. RESULTS: Thirty-one consecutive patients were recruited to undergo our ERP. Mean age of patients was 62.16 years. No patients died due to surgical complications. Nine of 31 patients experienced complications (29.03%), none requiring surgical intervention. According to Clavien grading, all complications were grade <2. CONCLUSION: The application of our ERP to our patients undergoing RC and VIP neobladder contributed to reduce postoperative morbidity.

Fast track surgery to reduce short-term complications following radical cystectomy and intestinal urinary diversion with Vescica Ileale Padovana neobladder: proposal for a tailored enhanced recovery protocol and preliminary report from a pilot study.

OBJECTIVE: Different fast track programs for patients undergoing radical cystectomy (RC) can be found in the current literature. The aim of this work was to develop a new enhanced recovery protocol (ERP). PATIENTS AND METHODS: The ERP was designed after a structured literature review focusing on reduced bowel preparation, standardized feeding, postoperative nausea, vomiting and pain control. In order to test the ERP, a pilot observational prospective cohort study was planned, enrolling all patients consecutively undergoing RC and Vescica Ileale Padovana (VIP) neobladder. These patients were compared with a matched group of subjects who had undergone RC and VIP neobladder before implementation of the ERP. To achieve good comparability, a propensity score-matching was performed. The primary aim was to assess the ERP's feasibility; the secondary outcome measures were early morbidity and mortality. RESULTS AND LIMITATIONS: After an exhaustive literature search and a multidisciplinary consultation, an ERP was designed. Nine consecutive patients participated in the pilot study and were compared to 13 patients treated before implementation of the ERP. We did not find any statistically significant difference in terms of mortality rate (none died peri- or postoperatively in both groups). The complication rate, according to the modified Clavien classification, was significantly lower in the ERP group (22.22 vs. 84.61%, p < 0.004). The major limitations are the low number of patients enrolled to test the protocol and the lack of randomization for the comparative evaluations. CONCLUSION: The introduction of our ERP was proven to be feasible in the management of patients undergoing RC and intestinal urinary diversion with VIP neobladder. The postoperative course was enhanced by a significant reduction in both nasogastric tube insertion and parenteral nutrition support, with early postoperative feeding. All these findings were associated with no deleterious effect on morbidity or mortality, indeed there was a reduced occurrence of postoperative complication rates.
