Epidemiology and risk factors in urolithiasis.

Riccardo Bartoletti; Tommaso Cai; Nicola Mondaini; F. Melone; Fabrizio Travaglini; Marco Carini; Michele Rizzo

Stone formation in the urinary tract affects about 5–10% of the population in industrialized countries, although it is very rare in other countries such as Greenland or Japan. The high incidence and recurrence rate contribute to making the urolithiasis a serious social problem. Nowadays, urolithiasis must be considered a ‘disease in evolution’ for several reasons, such as epidemiological changes, evolution of the methods used for diagnosis, and the treatment and prophylaxis of the population considered ‘at risk’ of stone disease. Some features of stone disease have changed over the last few years due to many social, economical and cultural factors that are described here. The increased prevalence of small urinary calculi has brought about a change in clinical symptoms, with frequent episodes of renal-ureteral colic, persistent pain and hydronephrosis. Similarly, the presence of residual fragments after extracorporeal shock wave lithotripsy has induced a radical change in the management of small calculi through the use of mini-invasive surgical techniques.

OBJECTIVES To review the cases of patients with suspected penile fracture and asses erectile and sexological outcomes. MATERIALS AND METHODS from 1987 to 2013 presented to the Urology Clinic of Trieste and at the AIED of Pordenone a total of 41 cases that were divided into two groups according to the timing of treatment: 18 patients with anamnestic diagnosis of penile fracture treated nonimmediately and 23 patients treated immediately after the trauma. For all patients we evaluated the type of treatment adopted, the occurrence of complications and reoperations and the follow-up. The erectile function was also evaluated through the IIEF, as well as the psychological impact of the trauma on social and sex life, using a psycho- sexological questionnaire. RESULTS Among patients treated immediately after the trauma 14 were subjected to surgery. About a year after surgery, penile curvature was reported in 1 patient, pain in 3 patients, urinary disorders in 1 patient, while none reported erectile dysfunction (ED). Out of these, only 3 patients underwent reoperation. Among those treated conservatively 1 patient reported curvature, 1 patient reported pain and none reported ED. Among patients who were admitted at a later date, 14 reported curvature and 4 reported pain whereas urinary disorders were reported in 1 and ED in 4 patients. From a psychological point of view, the trauma caused in most cases a fear of new trauma and of repercussions on erectile function and sensitivity. CONCLUSIONS The diagnosis is mainly clinical; however, radiological investigation is essential to confirm the diagnosis, assess the site and extent of the trauma and possible urethral involvement, so as to plan the most appropriate treatment. In addition, immediate treatment leads to better long-term results, with a lower incidence of ED and penile curvature. Psychologically, penile trauma intensifies the fear of reoccurrence; it decreases, however, with the passage of time.

Introduction We present a refinement to our original technique in MtF gender reassignment surgery. Our goal was to construct a neoclitoris, which is wet and covered with urethral neoprepuce. Since 1995 more than 300 transgender MtF patients have been operated at our institution. Our refinement has been applied to 12 cases and showed both excellent functional and cosmetic results during midterm follow-up. Patients and Methods During 2010 several sex reassignment surgeries have been performed using our new technique that includes: bilateral orchiectomy, removal of corpora cavernosa of the penis, formation of the neourethra with neomeatus, neovaginoplasty by inversion of penoscrotal skin flaps, construction of the neoclitoris with preservation of the neurovascular bundle and exterior vulva formation. The refinement consists in creating a neoclitoris embedded in urethral mucosa using urethral flaps. These flaps are in continuity with the previously spatulated urethra. The urethral plate is further incised distally in a Y fashion. The urethral flaps are sutured around the neoclitoris to form a neourethroclitoris covered by urethral neoprepuce, which resembles a real female clitoris. The neoclitoris is positioned in the anatomical position of the male suspensory ligament of the penis that is also the natural anatomical position of the female clitoris. Results With this method we are able to construct a clitoris with a normal sensitivity embedded in urethral mucosa that remains wet and hairless. It can be easily stimulated during sexual intercourse, as most of the patients reported great satisfaction and ability to reach orgasm. Discussion We want to emphasize how both the cosmetic results and functionality of the neovagina and neoclitoris are important in this type of surgery for the quality of life of our patients. We are still far from a perfect surgical solution, but we are further improving our technique and follow our aims step by step.

BACKGROUND Numerous surveys have been performed to determine the competence and the confidence of residents. However, there is no data available on the condition of Italian residents in urology. OBJECTIVE To investigate the status of training among Italian residents in urology regarding scientific activity and surgical exposure. DESIGN, SETTING, AND PARTICIPANTS A web-based survey that included 445 residents from all of the 25 Italian Residency Programmes was conducted between September 2015 and November 2015. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS The main outcomes were represented by scientific activity, involvement in surgical procedures, and overall satisfaction. RESULTS AND LIMITATIONS In total, 324 out of 445 (72.8%) residents completed the survey. Overall, 104 (32%) residents had not published any scientific manuscripts, 148 (46%) published ≤5, 38 (12%) ≤10, 26 (8%) ≤15, four (1%) ≤20, and four (1%) >20 manuscripts, respectively. We did not observe any differences when residents were stratified by sex (p=0.5). Stent positioning (45.7%), extracorporeal shock wave lithotripsy (30.9%), transurethral resection of bladder tumor (33.0%), hydrocelectomy (24.7%), varicocelectomy (17%), ureterolithotripsy (14.5%), and orchiectomy (12.3%) were the surgical procedures more frequently performed by residents. Overall, 272 residents (84%) expressed a good satisfaction for urology specialty, while 178 (54.9%) expressed a good satisfaction for their own residency programme. We observed a statistically decreased trend for good satisfaction for urology specialty according to the postgraduate year (p=0.02). CONCLUSIONS Italian Urology Residency Programmes feature some heavy limitations regarding scientific activity and surgical exposure. Nonetheless, satisfaction rate for urology specialty remains high. Further improvements in Residency Programmes should be made in order to align our schools to others that are actually more challenging. PATIENT SUMMARY In this web-based survey, Italian residents in urology showed limited scientific productivity and low involvement in surgical procedures. Satisfaction for urology specialty remains high, demonstrating continuous interest in this field of study from residents.

The Infertile Male-1: Clinical Features

Giovanni Liguori; Carlo Trombetta; Bernardino de Concilio; Alessio Zordani; Michele Rizzo; Stefano Bucci; Emanuele Belgrano

Male infertility affects 10% of couples and is treatable in many cases. The evaluation of infertility is initiated typically after 1 year of failure to conceive. Clinical evaluation of the infertile man requires a complete medical history, physical examination, and laboratory studies in order to identify and treat correctable causes of subfertility and recognize those who are candidates for assisted reproductive technologies, those who are sterile and should consider adoption or artificial insemination using donor sperm, and those who should undergo genetic screening. Although pregnancies can be achieved without any evaluation other than a semen analysis, this test alone is insufficient to adequately evaluate the male patient. Treatment of correctable male-factor pathology is cost effective, does not increase the risk of multiple births, and can spare the woman invasive procedures and potential complications associated with assisted reproductive technologies.

Profilassi antibiotica nelle procedure urologiche

Michele Rizzo; Carlo Trombetta

Antibiotic prophylaxis in urological procedures Thousands of patients receive every day an antibiotic prophylaxis before diagnostic or therapeutic urological procedures. Aim of antibiotic prophylaxis is to reduce the risk of infective complications, unfortunately good quality evidences for the best choice of prophylaxis strategy are often lacking. Nowadays antimicrobial resistance is a major health problem caused primarily by overuse of antibiotics. It is the responsibility of all physicians to practice antibiotic stewardship avoiding the unnecessary use of this precious drugs. Given the previous consideration prophylaxis should be chosen on the base of the best evidences, if evidences are lacking prophylaxis should be tailored on the base of each patient individual features and risk factor for infection complications. This narrative review of antibiotic prophylaxis in urological procedure resumes the principle to follow for the correct management of antibiotic prophylaxis in urological procedure.

Introduction and objectives The investigation of the neovaginal microflora can help during the post-surgery follow-up of transgender women in order to ensure a proper therapy in case of the onset of an infectious disease. We mapped the neovaginal microflora during the early perioperative days after male to female (M-F) gender reassignment surgery in HIV, HBV and HCV seronegative and healthy transsexual women. Materials and Methods Between November 2016 and January 2017 we collected 2 neovaginal swabs (one in the neo-vaginal fundus and one in the proximity of the urethral meatus) during the early perioperative days from 8 patients (pts) who underwent M-F gender surgical reassignment. The V3-16S rRNA Next Generation Sequencing (NGS) and a multiplex PCR technology were used to investigate the microbial composition and the presence of Sexual Transmitted Infections, respectively. QIIME 1.8.01 was used to process the NGS data.

BACKGROUND The aim of this study was to assess the efficacy of emergency extracorporeal shockwave lithotripsy (eSWL) as first-line treatment in patients with acute colic due to obstructive ureteral stone. METHODS Seventy-four patients were randomized to emergency SWL within 12 hours (eSWL group) and deferred SWL later than 3 days (dSWL group). Follow-up included ultrasound, KUB (kidney-ureter-bladder) radiography and CT (computed tomography) scan at 24 hours, 7 days, 1 and 3 months from the treatment. When necessary, repeated SWL (re-SWL) or ureteroscopy (auxiliary-URS) was performed. Preoperative and postoperative data were compared and stone free rates (SFR) and efficiency quotients (EQ) were evaluated. Analyses were performed using SAS software. RESULTS Complete data of 70 patients were collected. 36 underwent eSWL and 34 dSWL. The mean patient age was 48.7. Mean stone size was 9.8 mm (CI 95%: 8.9-10.8). 25 (35.7%) were proximal and 45 (64.3%) distal. Mean SWL energy was 19.2 kV (CI 95%: 18.5-19.9) and mean number of shocks was 2657 (CI 95%: 2513-2802). eSWL patients needs less auxiliary-URS than dSWL patients (13.9% vs. 44.1%, P=0.039) and less re-SWL sessions (8.3% vs. 32.4%, P=0.093). SFR at 24 hours was 52.8% and 11.8% (P<0.001) and the EQ at 3 months was 79.1% and 57.5% in the eSWL and dSWL group respectively. Patients from the dSWL group spent more time in the hospital (2.21 vs. 1.36 days, P=0.046) and complication rates between the two groups were similar. CONCLUSIONS eSWL is a safe procedure and delivers high SFR even within 24 hours especially for <10 mm stones. It is able to reduce the number of auxiliary procedures and hospitalization.

Pulmonary recurrence from prostate cancer and biochemical remission after metastasis directed therapy. A case report

Riccardo Boschian; Michele Rizzo; Lorenzo Zandonà; Carlo Trombetta; Giovanni Liguori

We report a case of a 69-years-old man who presented with a solitary 1 cm nodule in the lower lobe of the left lung almost 3 years after radical prostatectomy for pT3aN0M0, Gleason score 4+3 disease, without evidence of osseous or lymphatic spread. Surgical resection of the pulmonary lobe confirmed the metastatic nature of the lesion, with subsequent reduction of serum PSA to undetectable levels. After 2 years from the metastasis resection, serum PSA is still undetectable, without the necessity of additional treatments. Solitary pulmonary metastases from prostate cancer (Pca) are rare in clinical practice, with only 29 previous cases described besides the one that we present.
