RESUMO

INTRODUCTION: To evaluate the intermediate-term outcomes of thulium vapoenucleation of the prostate (ThuVEP) and thulium vaporesection of the prostate (ThuVaRP) in patients with benign prostate obstruction (BPO). MATERIALS AND METHODS: A bicentric retrospective matched-paired comparison of patients treated by ThuVEP (n = 80) or ThuVaRP (n = 80) was performed. The patients were preoperatively assessed with International Prostate Symptom Score (IPSS), quality of life (QoL), post-void residual urine (PVR), maximum urinary flow rate (Qmax), prostatespecific antigen (PSA) and re-evaluated at 12- and 24-month follow-up. RESULTS: Median prostate volume was 65 mL and not different between the groups. The immediate re-operation rate was significantly different between ThuVEP and ThuVaRP (5 vs. 0%, p ≤ 0.0434). IPSS, QoL, Qmax and PVR had improved significantly compared to preoperative assessment in both groups at 12- and 24-month follow-up (p ≤ 0.001). Median Qmax (18.2 vs. 21.0 mL/s) and PVR (29.4 vs. 0 mL) were significantly different between ThuVEP and ThuVaRP at 24-month follow-up (p ≤ 0.001), while IPSS and QoL showed no differences between the groups. However, the PSA reduction was significantly higher after ThuVEP compared to ThuVaRP (78.93 vs. 23.39%, p ≤ 0.006) at 24-month follow-up. CONCLUSIONS: ThuVEP and ThuVaRP are safe and efficacious procedures for patients with BPO. Although the peri-operative re-intervention rates were lower after ThuVaRP, the low PSA reduction rate after ThuVaRP at 24-month follow-up favours the ThuVEP procedure.

RESUMO

OBJECTIVES: Analyze the oncologic and functional outcomes in patients affected by low risk prostate cancer underwent prostate cryotherapy. Materiasl and methods: It's a prospective tricentric study of 434 patients treated with prostate cryoablation for low risk prostate cancer. By low risk we refer to the D'Amico's risk classification. Two cycles of freezing/thawing are run for each patient following the technique described by Onik. RESULTS: For the 434 patients, the median age was 66 years with a standard deviation of ± 6.68, the average PSA was 6.17 ng/d/L, the median 5.55 with a standard deviation of ± 2.13, the mean prostate volume was 35.59 cc, the median 34.00 cc, with a standard deviation of ± 7.89. Biochemical failure occurred in 67 patients (15.4%). Pre-operative erectile function in men was distributed as follows: severe in 95 patients (19.2%), moderate in 95 (19.2%), medium-moderate in 180 (36.4%), mild in 92 (18.6%), with no dysfunction in 32 (6.5%) patients. Post-operative erectile function, measured 1 month after cryotherapy, was distributed as follows: severe in 321 (65%) patients, moderate in 69 (14%), medium-moderate in 79 (16%), mild in 23 (4.7%), and no dysfunction in only 2 patients (0.4%). Post-operative erectile function after 3 months was distributed as follows: severe in 233 (47.2%) patients, moderate in 66 (13.4%), medium-moderate in 122 (24.7%), mild in 65 (13.2%), and no dysfunction in 8 patients (1.6%). Urinary incontinence was present in 21 patients (4.8%) after 3 months while it dropped to 13 patients (2.9%) after 6 months. CONCLUSIONS: Cryotherapy in the treatment of prostate cancer remains a viable alternative. The availability of new cryoprobes and the use of new diagnostic means such as fusion magnetic resonance will make this more precise and more effective method.

RESUMO

PURPOSE: Thulium vaporesection of the prostate (ThuVARP) is a new and safe approach for patients receiving anticoagulant therapy in whom transurethral resection of the prostate (TURP) may possess a high bleeding risk. We aimed to demonstrate the efficacy and safety of ThuVARP in patients receiving oral antiplatelet/anticoagulant (OAP/OAC) therapy. MATERIALS AND METHODS: A total of 103 patients who underwent ThuVARP between 2011 and 2013 were enrolled in the study. Patients were divided into 2 groups. Group A consisted of 47 patients who underwent low molecular weight heparin (LMWH) bridging and group B consisted of 56 patients who were operated on while receiving OAP/OAC therapy. RESULTS: The drop in hemoglobin levels in the pre- and postoperative periods was significantly higher in group A than in group B. When subgroups were analyzed, the mean drop in hemoglobin was significantly lower in the warfarin and ticlopidine subgroups of group B than in group A. International Prostate Symptom Scores were significantly lower 3, 12, 18, and 24 months after surgery in group A than in group B. Quality of life scores, maximal flow rate values, and postmicturition residual urine volumes (mL) were similar between the 2 groups. A total of 38 and 41 patients in groups A and B, respectively, had no complications. CONCLUSIONS: Our study showed the safety profile of continuing different OAP/OAC therapies in terms of bleeding problems in patients undergoing ThuVARP. We strongly recommend abandoning LMWH bridging and maintaining the OAP/OAC regimen patients are already receiving.

RESUMO

PURPOSE: Interstitial cystitis/painful bladder syndrome (IC/PBS) is a chronic pain syndrome and a chronic inflammatory condition prevalent in women that leads to urgency, sleep disruption, nocturia and pain in the pelvic area, to the detriment of the sufferer's quality of life. The aim of this review is to highlight the newest diagnostic strategies and potential therapeutic techniques. METHODS: A comprehensive literature review was performed on MEDLINE, PubMed, and Cochrane databases gathering all literature about "Interstitial cystitis" and "Painful Bladder Syndrome". Visual analogue scales, epidemiological strategies, pain questionnaires and similar techniques were not included in this literature survey. RESULTS: The etiology, exact diagnosis and epidemiology of IC/PBS are still not clearly understood. To date, its prevalence is estimated to be in the range of 45 per 100,000 women and 8 per 100,000 men, whereas joint prevalence in both sexes is 10.6 cases per 100,000. There are no "gold standards" in the diagnosis or detection of IC/PBS, therefore, several etiological theories were investigated, such as permeability, glycosaminoglycans, mast cell, infection and neuroendocrine theory to find new diagnostic strategies and potential biomarkers. CONCLUSION: Due to the fact that this disease is of an intricate nature, and that many of its symptoms overlap with other concomitant diseases, it could be suggested to classify the patients with emphasis on the phenotype, as well as their symptom clusters, to tailor the diagnostic and management choices according to the observed biomarkers.

RESUMO

OBJECTIVES: To explore whether serum and urinary advanced glycation end-products (AGEs) are related to urinary symptoms and bladder dysfunctions in diabetic patients. METHODS: Forty-seven patients with type 2 Diabetes mellitus (T2DM) and lower urinary tract symptoms (LUTS) were enrolled. LUTS evaluation was performed by IPSS (International Prostatic Symptoms Score), QoL (quality of life), OAB (overactive bladder). ICI-SF (International Consultation on Incontinence - short form) quaestionneires; ultrasound examination, evaluation of postvoid residual (PVR), uroflowmetry, cystometry with pressure-flow study (PFS) were performed to detect bladder dysfunctions. Serum and urinary AGEs were quantified by ELISA method. RESULTS: Patients were divided into four subgroups: (i) normal-detrusor-contractility + normal- detrusor-activity (1 ♂ [4.8%] and 4 ♀ [21%]), (ii) impaired-detrusor-contractility + normal-detrusor- activity (4 ♂ [19.1%] and 0 ♀), (iii) normal-detrusor-contractility + detrusor-overactivity (1 ♂ [4.8%] and 6 ♀ [31.6%]), (iv) impaired-detrusor-contractility + detrusor-overactivity (15 ♂ [71.4%] and 9 ♀ [47.4%]). Serum AGEs were 12.2 ± 5.5 in men and 10.4 ± 5.6 in women; urinary AGEs were 1.5 ± 1.1 in men and 2.5 ± 1.6 in women. Serum AGEs exhibited a positive correlation with IPSS (P < 0.05) and OAB-q scores (P < 0.01). Increased serum AGEs were associated with a significant reduction in the parameters reflecting impaired detrusor contractility with simultaneous reductions of urinary AGEs (P < 0.01). A greater correlation was observed between serum AGEs and subgroup 4 (P < 0.05). CONCLUSIONS: Serum AGEs seem to be early markers of diabetic complications and appear to be related to LUTS and bladder dysfunctions.

RESUMO

OBJECTIVE: To evaluate our experience in patients undergoing hybrid transvaginal natural orifices transluminal endoscopic surgery (NOTES) nephrectomy and evaluate the sexual functions in the postoperative period. MATERIALS AND METHODS: Prospective data of 71 patients with renal tumors who underwent hybrid NOTES radical nephrectomy in three different centers were collected from March 2010 to October 2015. Patient and surgical characteristics were recorded. Sexual function was evaluated using the Female Sexual Function Index questionnaire the day prior to the operation and 3 months after. RESULTS: The mean age, tumor size, and operation duration were 66.16 ± 11.21, 8.51 ± 3.31 cm, and 119.94 ± 21.38 minutes, respectively. Five patients were immediately reoperated due to bleeding from uterine veins. The complication risk increases significantly with increasing tumor size. Among the whole cohort, even the Female Sexual Function Index score differences are small; there is a statistically significant decrease in the postoperative period in all domains except sexual satisfaction. In fact, the patients reported unaltered sexual function after surgery and satisfaction with the result when asked directly. In subgroup analyses, in nulliparous patients (n = 60), arousal, sexual desire, orgasm, and satisfaction domains have no significant differences in pre- and postoperative periods. CONCLUSIONS: Hybrid NOTES nephrectomy is a feasible, safe operation that can be performed for large renal tumors. Due to incisions in the vaginal wall for specimen retrieval, sexual function can be altered in the postoperative period. So patient selection, preoperative evaluation, and close follow-up are mandatory. With this in mind, we strongly support the use of hybrid transvaginal NOTES nephrectomy for large renal tumors especially in nulliparous patients.

RESUMO

Spontaneous subcapsular renal hematoma is a rare condition in clinical practice. It is caused by renal cysts, benign and malignant renal tumors, vascular lesions, and antiplatelet or anticoagulant therapy. In this paper we report an unusual case of rupture of a renal cyst of a 66-year-old male patient during an aortic and iliac endovascular procedure for a massive calcified atheroma above the iliac bifurcation. We suspected that the bolus of high weight molecular heparin given during the procedure caused the rupture of the cyst. According to the literature, this is the first case of renal cyst rupture during an endovascular aortic procedure after administering a high weight molecular heparin bolus.

RESUMO

INTRODUCTION: To evaluate the short-term results of thulium vaporesection of the prostate (ThuVEP) and thulium vapoenucleation of the prostate (ThuVARP) in patients with benign prostatic obstruction on oral anticoagulants (OA). METHODS: A 3-centre retrospective matched-paired comparison of patients treated by ThuVEP (n = 26) or ThuVARP (n = 26) was performed. Thirty-four patients were on aspirin/ticlopidin, 7 on clopidogrel or clopidogrel and aspirin, and 11 on phenprocoumon at the time of surgery. RESULTS: Haemoglobin decrease was higher after ThuVEP compared to ThuVARP (1.5 vs. 0.3 g/dl, p < 0.001). The rate of postoperative blood transfusions (3.9 vs. 0%), clot retention (3.9 vs. 0%), and re-operation (7.7 vs. 0%) was not different between ThuVEP and ThuVARP (p = 0.274). Catheterization time was shorter for ThuVARP (1 vs. 2 days, p < 0.01). Qmax was significantly higher after ThuVEP at 6-month follow-up (31 vs. 21.5 ml/s, p < 0.001), while improvements in International Prostate Symptom Score, quality of life, and post-voiding residual urine showed no differences between the groups. Urethral or bladder neck strictures did not occur during the 6-month follow-up in both groups. CONCLUSIONS: ThuVEP and ThuVARP are safe and efficacious procedures in patients on OA. Although patients assigned to ThuVEP had higher Qmax at 6-month follow-up, ThuVARP resulted in similar functional outcomes.

RESUMO

Transrectal Ultrasound (TRUS) guided prostate biopsy is regarded as the gold standard for prostate cancer diagnosis. The majority of patients perceive TRUS-guided prostate biopsy as a physically and psychologically traumatic experience. We aimed to compare in this paper the efficacy of three different anesthesia techniques to control the pain during the procedure. MATERIALS AND METHODS: 150 patients who underwent transrectal ultrasound (TRUS) guided prostate biopsy were randomly divided into three groups. Group A included 50 patients who received one hour before the procedure a mixture of 2.5% lidocaine and 2.5% prilocaine, Group B: 50 patients who received intrarectal local anesthetic administration (lidocaine 5 ml 10%) and lidocaine local spray 15 % and Group C included 50 patients who received periprostatic block anesthesia (lidocaine 10 ml 10%). Visual analogue scale (VAS) of patients in different groups was evaluated at the end of the biopsy and 30 minutes after the procedure. RESULTS: The VAS of patients in Group A was 1.32 ± 0.65 (VAS I) and 2.47 ± 0.80 (VAS II). In group B the VAS of patients was 1.09 ± 0.47 (VAS I) and 1.65 ± 0.61 (VAS II). In group C the VAS of patients was 2.63 ± 0.78 (VAS I) and 1.70 ± 0.85 (VAS II). There was no statistically significant difference in term of VAS I between group A and B. A statistically significant difference was determined in terms of VAS II between group A and B. There was no statistically significant difference in term of VAS between group B and C. CONCLUSIONS: The most effective of the three methods for pain control we used was intrarectal local anesthetic administration and lidocaine local spray 15% that enables an ideal patient comfort.

RESUMO

PURPOSE: To assess the performance of prostate health index (PHI) and prostate cancer antigen 3 (PCA3) when added to the PRIAS or Epstein criteria in predicting the presence of pathologically insignificant prostate cancer (IPCa) in patients who underwent radical prostatectomy (RP) but eligible for active surveillance (AS). METHODS: An observational retrospective study was performed in 188 PCa patients treated with laparoscopic or robot-assisted RP but eligible for AS according to Epstein or PRIAS criteria. Blood and urinary specimens were collected before initial prostate biopsy for PHI and PCA3 measurements. Multivariate logistic regression analyses and decision curve analysis were carried out to identify predictors of IPCa using the updated ERSPC definition. RESULTS: At the multivariate analyses, the inclusion of both PCA3 and PHI significantly increased the accuracy of the Epstein multivariate model in predicting IPCa with an increase of 17 % (AUC = 0.77) and of 32 % (AUC = 0.92), respectively. The inclusion of both PCA3 and PHI also increased the predictive accuracy of the PRIAS multivariate model with an increase of 29 % (AUC = 0.87) and of 39 % (AUC = 0.97), respectively. DCA revealed that the multivariable models with the addition of PHI or PCA3 showed a greater net benefit and performed better than the reference models. In a direct comparison, PHI outperformed PCA3 performance resulting in higher net benefit. CONCLUSIONS: In a same cohort of patients eligible for AS, the addition of PHI and PCA3 to Epstein or PRIAS models improved their prognostic performance. PHI resulted in greater net benefit in predicting IPCa compared to PCA3.

RESUMO

OBJECTIVES: Locally advanced prostate cancer may cause several complications such as haematuria, bladder outlet obstruction, and renal failure due to the ureteral obstruction. Various treatments have been suggested, including radiotherapy, antifibrinolytics, bladder irrigation with alum solution, transurethral surgery and angioembolization, none of which have proven effectiveness. In the last years cryoablation has become a valid therapeutic option for prostate cancer. In our experience we used this 'new' technique as haemostatic therapy. METHODS: We selected four patients with gross haematuria affected by locally advanced hormone refractory prostate cancer, who had already been treated with primary radiotherapy. We used third-generation cryotherapy: under ultrasonographic guidance, we inserted six cryoprobes, two in each of the vascular pedicles reaching at least -60°C, and three thermometers. We then induced two freeze-thaw cycles. RESULTS: After the operation the haematuria stopped in all patients and at 9-month follow up we observed a mean of four red cells (range three to five) in the urinary sediment with no evidence of bacteriuria. Prostate volume, prostate-specific antigen and postmicturition residue were significantly reduced. Qmax improved significantly too. CONCLUSION: Our experience has given us good results with minimal intra- and postoperative complications. We think that haemostatic cryotherapy as a palliative approach for locally advanced prostate cancer could represent a valid treatment option and more consideration could be given to its use.

RESUMO

Cadmium (Cd) causes male infertility. There is the need to identify safe treatments counteracting this toxicity. Flavocoxid is a flavonoid that induces a balanced inhibition of cyclooxygenase (COX)-1 and COX-2 peroxidase moieties and of 5-lipoxygenase (LOX) and has efficacy in the male genitourinary system. We investigated flavocoxid effects on Cd-induced testicular toxicity in mice. Swiss mice were divided into 4 groups: 2 control groups received 0.9% NaCl (vehicle; 1 ml/kg/day) or flavocoxid (20 mg/kg/day ip); 2 groups were challenged with cadmium chloride (CdCl2; 2 mg/kg/day ip) and administered with vehicle or flavocoxid. The treatment lasted for 1 or 2 weeks. The testes were processed for biochemical and morphological studies. CdCl2 increased phosphorylated extracellular signal-regulated kinase (p-ERK) 1/2, tumor necrosis factor (TNF)-α, COX-2, 5-LOX, malondialdehyde (MDA), B-cell-lymphoma (Bcl)-2-associated X protein (Bax), follicle-stimulating hormone (FSH), luteinizing hormone (LH), transforming growth factor (TGF) -ß3, decreased Bcl-2, testosterone, inhibin-B, occludin, N-Cadherin, induced structural damages in the testis and disrupted the blood-testis barrier. Many TUNEL-positive germ cells and changes in claudin-11, occludin, and N-cadherin localization were present. Flavocoxid administration reduced, in a time-dependent way, p-ERK 1/2, TNF-α, COX-2, 5-LOX, MDA, Bax, FSH, LH, TGF-ß3, augmented Bcl-2, testosterone, inhibin B, occludin, N-Cadherin, and improved the structural organization of the testis and the blood-testis barrier. Few TUNEL-positive germ cells were present and a morphological retrieval of the intercellular junctions was observed. In conclusion, flavocoxid has a protective anti-inflammatory, antioxidant, and antiapoptotic function against Cd-induced toxicity in mice testis. We suggest that flavocoxid may play a relevant positive role against environmental levels of Cd, otherwise deleterious to gametogenesis and tubular integrity.

RESUMO

Neuronal apoptosis inhibitory protein (NAIP) and survivin might play an important role in testicular function. We investigated the effect of PDRN, an agonist of adenosine A2A receptor, on testicular NAIP and survivin expression in an experimental model of varicocele. After the creation of experimental varicocele (28 days), adolescent male Sprague-Dawley rats were randomized to one of the following treatments lasting 21 days: vehicle, PDRN (8 mg/kg i.p., daily), PDRN + 3,7-dimethyl-propargylxanthine (DMPX, a specific adenosine A2A-receptor antagonist, 0.1 mg/kg i.p., daily), varicocelectomy, and varicocelectomy + PDRN (8 mg/kg i.p., daily). Sham-operated animals were used as controls. Animals were then euthanized and testis expression of NAIP and survivin was evaluated through qRT-PCR, western blot, and immunohistochemical analysis. Spermatogenetic activity was also assessed. NAIP and survivin expressions were significantly reduced following varicocele induction when compared to sham animals whereas PDRN-treated rats showed an increase in NAIP and survivin levels. Immunohistochemistry revealed an enhanced expression of NAIP and survivin with a characteristic pattern of cellular localization following PDRN treatment. Moreover, administration of PDRN significantly restored spermatogenic function in varicocele rats. PDRN may represent a rational therapeutic option for accelerating recovery from depressed testicular function through a strategic modulation of apoptosis in experimental varicocele.

RESUMO

Transcaval ureter is a rare congenital anomaly characterized by an inferior cava vein duplication producing a vascular ring around the right ureter, usually determining hydroureteronephrosis. The knowledge of this vascular anomaly on imaging examinations permits to avoid erroneous diagnosis of retroperitoneal masses or adenopathy and preoperatively advise the surgeon of potential sources of complications. We describe a case of transcaval ureter studied with multidetector computed tomography. To our knowledge, this is the first case in which computed tomography multiplanar and volume-rendering reconstructions show this rare anomaly.

RESUMO

OBJECTIVE: To assess the proportion of patients with Peyronie's Disease (PD) and the possible association with its potential risk factors in the general population of the central and western Sicily in our weekly andrological outpatient clinic. MATERIALS AND METHODS: We recruited a sample of 279 consecutive patients consulting our andrological outpatient clinic. Two arms were created: the first one composed by PD patients (men with symptoms suggestive for PD), the second one composed by patients with other andrological diseases (control arm). For each patient we evaluated the age, cigarette smoking, diabetes, blood hypertension and erectile function. In the PD arm we administered validated questionnaires to determine the erectile function status by the International Index of Erectile Function 5 (IIEF-5) and the pain status during erection by the Visual Analogue Scale (VAS). A univariate analysis was conducted using R software. RESULTS: We enrolled 279 consecutive patients. The number of PD patients was 97 (34,7%). The univariate analysis showed a correlation between PD and cigarette smoking (p = 0.0242), blood hypertension (p < 0.001), erectile dysfunction (p < 0.001). No significant association was observed between diabetes and PD (p = 0.358). The median age of PD arm was 60 years and the median age of the control arm was 63,5 years; therefore the median age of PD arm resulted lower than the median age of the control arm (p = 0,031). CONCLUSIONS: Peyronie's disease is more common than we might think; furthermore it can be diagnosed among young patients. According to our results, cigarette smoking and blood hypertension may be considered statically significant risk factors for developing PD. On the contrary diabetes seems not to be a risk factor for PD. According to our results PD should be sought also in young patients. Further studies are necessary to confirm that removing the indicated risk factors may reduce the incidence of PD.

RESUMO

Diagnosis of synchronous primary genitourinary tumors are uncommon. Thus far, about 50 cases of synchronous renal tumors have been reported in the literature. We present for the first time a case of a 83-year-old man presenting in the same kidney two separate primary malignancies, a TCC of the renal pelvis and a papillary renal cell carcinoma Type 1. Considered the increased incidence of genitourinary tumors, in presence of a small renal tumor with hematuria, in our opinion, is necessary to pay attention to the diagnostic phase for the chance to highlight an urothelial cancer.
