Traumatic testicular dislocation in the abdomen: diagnosis and management.

Testicular dislocation in the abdomen after scrotal trauma is a rare and sometimes unrecognised event.Early detection and timely management reduce possible complications which include the risk of fertility loss, endocrine dysfunction, and future malignancy.We present the case of a man who suffered a traumatic dislocation of the right testis in the abdomen after a motorcycle crash. The large scrotal haematoma did not permit adequate physical examination. Furthermore, during the clinical management of the polytrauma, the main focus was on active arterial bleeding, multiple pelvic fractures and clinical investigation of the integrity of the lower urinary tract. Therefore, the diagnosis and surgical management of the testicular dislocation were delayed.The patient underwent abdominal-inguinal surgical exploration, haematoma evacuation, identification of the right testis and right orchidopexy.After 6 months, the right testis of the patient is of regular volume, consistency and physiologic echogenicity on ultrasound evaluation.Hormonal evaluation and semen analysis were normal after 3 months.

Continence-Sparing Techniques in Radical Prostatectomy: A Systematic Review of Randomized Controlled Trials.

Background: Numerous continence-sparing radical prostatectomy techniques have been developed to enhance postoperative early continence (EC) recovery; however, evidence regarding the best approach remains controversial. The objectives are to provide a critical appraisal of various prostatectomy techniques, based on the evidence of quality-assessed randomized control trials (RCTs); to summarize the immediate continence and the EC reported; and to propose a new standardization for continence outcomes reporting. Methods: Data acquired from five medical registries were reported to Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) standards. Evidence from published, English, full-text RCTs reporting postoperative urinary continence outcomes within 6 months from surgery was included. The heterogeneity of surgical techniques and continence definitions did not allow a meta-analysis. All RCTs were critically appraised, and quality assessed. Results: In total, 39 RCTs were included: 19 of 39 studies were low-quality RCTs, presenting small cohort, monocentric, or single-surgeon data. The best RCT-supported evidence is in favor of robot-assisted radical prostatectomy (RARP) compared with laparoscopic radical prostatectomy (LRP) and of the Retzius-sparing (RS) technique over the traditional prostatectomy. Other techniques such as bladder neck and puboprostatic ligament (PPL) preservation, posterior reconstruction with or without combination of anterior suspension technique, and nerve-sparing (NS) approach seem to enhance EC. Oppositely, the endopelvic fascia preservation, bladder neck mucosa eversion/plication/slings, and the selective ligature of dorsal venous complex (DVC) were not significantly associated with EC improvements. RCTs are lacking on pubovesical complex-sparing, seminal vesicle preservation, anterior reconstruction of the puboprostatic collar, musculofascial reconstruction, and DVC suspension to the periosteum of the pubic bone techniques. Conclusions: RARP and RS have high-quality evidence supporting their ability to enhance postoperative EC recovery. NS, bladder neck, and PPL preservation may contribute to better EC recovery, although the evidence level is low. Further multicenter RCTs are needed to establish the optimal combination of standard surgical techniques. A new continence outcome-reporting standardization was proposed.

"Urethral-Sparing" Robotic Radical Prostatectomy: Critical Appraisal of the Safety of the Technique Based on the Histologic Characteristics of the Prostatic Urethra.

BACKGROUND: The prostatic urethra (PU) is conventionally resected during robot-assisted radical prostatectomy (RALP). Recent studies demonstrated the feasibility of the extended PU preservation (EPUP). AIMS: To describe the histologic features of the PU. METHODS: The PU was evaluated using cystoprostatectomy and RALP specimens. Cases of PU infiltration by prostate cancer or distortion by benign hyperplastic nodules were excluded. The thickness of the chorion and distance between the urothelium and prostate glands were measured. Prostate-specific antigen expression in the PU epithelium was evaluated with immunohistochemistry. Descriptive statistics were used. RESULTS: Six specimens of PU were examined. Histologically, the following layers of the PU were observed: (1) urothelium with basal membrane, (2) chorion, and (3) prostatic peri-urethral fibromuscular tissue. The chorion measures between 0.2 and 0.4 mm. There is not a distinct urethral muscle layer, but rather muscular fibers that originate near the prostatic stroma and are distributed around the PU. This muscular tissue appears to be mainly represented in the basal and apical urethra, but not in the middle urethra. The mean distance between the chorion and prostatic glands is 1.74 mm, with significant differences between base of the prostate, middle urethral portion, and apex (2.5 vs. 1.49 vs. 1.23 mm, respectively). PSA-expressing cells are abundant in the PU epithelium, coexisting with urothelial cells. CONCLUSIONS: The exiguity of thickness of the PU chorion, short distance from glandular tissue, and coexistence of PSA-expressing cells in the epithelium raise important concerns about the oncologic safety of EPUP.

Antegrade left ureterolithotripsy in a patient with previous psoas-hitch ureteral reimplantation.

A standard surgical treatment of distal ureteric defects is represented by the ureteroneocystostomy-ureteric reimplantation. However, the procedure involves an anatomical alteration of the ureterovesical (neo)junction that often hinders the retrograde catheterisation of the reimplanted ureter.We describe a case of antegrade ureterolithotripsy (AULT) in a psoas-hitch reimplanted ureter. A woman with severe left hydronephrosis supported by a subcentimetric proximal ureteral stone in a psoas-hitch reimplanted ureter was referred to our unit. Retrograde ureteroscopy was unsuccessful due to impossibility in incannulating the ureteral neo-orifice. Following the placement of a percutaneous nephrostomy, percutaneous AULT through ureteral sheath was successfully performed with complete treatment of the stone.AULT may represent a viable alternative in the management of ureteral stones when the upper urinary tract is not amenable to retrograde ureteroscopy. In experienced hands, the procedure is straightforward and may avoid the adoption of transabdominal approaches.

Fournier's gangrene with prostatic and bladder trigone colliquation: a suggested treatment algorithm.

Fournier's gangrene (FG) is an infectious necrotising fasciitis of the perineum and genital regions with a high mortality rate. We report the case of a man in his 70s with FG who presented with bladder trigone and prostate colliquation. Bulbar and penile urethra were also injured with multiple fenestrations. Bilateral percutaneous nephrostomy positioning followed by the placement of occluding ureteral catheters preceded the surgical debridement of the necrotic tissues and protective colostomy. There followed periodic sessions of surgical debridement and VAC therapy. The persistent perineal urinary leak required the crafting of a suprapubic surgical cystostomy with bladder neck obliteration through double-layer raphy. The cystostomy maintained the healing tissues free from the constant and damaging urine action. This report describes the successful multistep approach of an FG with deep involvement and colliquation of the bladder neck and prostate reaching the Denonvilliers fascia that ensured the correct healing of tissues.

Double-J stent placement during laparoscopic ureterolithotomy: the "seagull" technique.

OBJECTIVE: To present a new technique of double-j stent (DJ) placement during laparoscopic transperitoneal ureterolithotomy (LUL). PATIENTS AND METHODS: Following the extraction of the stone, a 6 French DJ open-end stent is prepared: two straight-tip hydrophilic guidewires are inserted into the appropriate lateral holes of the stent, as identified by the preoperative evaluation of the CT scan. Approximately 5 centimeters of each wire protrude from the proximal and distal ends of the stent to straighten its terminal curl, thus resembling the wings of a flying seagull. The remaining proximal portions of both guide wires are left within each guidewire dispenser. The two ends of the stent are grasped together in a U-fashion and inserted into the abdomen through a 10mm port. Once in the abdomen, the longer segment of the stent is inserted and pushed into the ureterotomy until it reaches the target site. The guide wire is then removed. The same procedure is repeated for the other end of the stent. A brief literature review on the currents techniques of laparoscopic DJ placement is also presented. RESULTS: Analyzing the outcomes of 21 LUL, the "seagull" technique is time-saving and safe. No perioperative complications were encountered. There is no risk of enlarging or tearing the ureterotomy and no need for patient replacement, extra cystoscopic or ureteroscopic procedures as well as of using modified guidewires and closed-tip stents. CONCLUSION: We described our step-by-step technique for DJ placement during LUL.

Endothelial Dysfunction, Erectile Deficit and Cardiovascular Disease: An Overview of the Pathogenetic Links.

Erectile dysfunction (ED) is a condition with multifactorial pathogenesis, quite common among men, especially those above 60 years old. A vascular etiology is the most common cause. The interaction between chronic inflammation, androgens, and cardiovascular risk factors determines macroscopically invisible alterations such as endothelial dysfunction and subsequent atherosclerosis and flow-limiting stenosis that affects both penile and coronary arteries. Thus, ED and cardiovascular disease (CVD) should be considered two different manifestations of the same systemic disorder, with a shared aetiological factor being endothelial dysfunction. Moreover, the penile arteries have a smaller size compared with coronary arteries; thus, for the same level of arteriopathy, a more significant blood flow reduction will occur in erectile tissue compared with coronary circulation. As a result, ED often precedes CVD by 2-5 years, and its diagnosis offers a time window for cardiovascular risk mitigation. Growing evidence suggests, in fact, that patients presenting with ED should be investigated for CVD even if they have no symptoms. Early detection could facilitate prompt intervention and a reduction in long-term complications. In this review, we provide an overview of the pathogenetic mechanisms behind arteriogenic ED and CVD, focusing on the role of endothelial dysfunction as the common denominator of the two disorders. Developed algorithms that may help identify those patients complaining of ED who should undergo detailed cardiologic assessment and receive intensive treatment for risk factors are also analyzed.

Unusual case of infectious endocarditis in a patient subjected to transurethral resection of the prostate (TURP) without cardiovascular risk factors. / Endocarditis en un paciente sujeto a RTU de próstata sin factores de riesgo cardiovascular.

OBJECTIVE: Transurethral resection of the prostate (TURP) is the gold standard for the treatment of obstructive prostatic hyperplasia. A bacteremia leading to infectious endocarditis (IE) can be the result of urological procedures. IE post TURP is rare. METHODS: We report an unusual case of an infectious endocarditis complicating TURP for benign prostatic hyperplasiain absence of known previous cardiovascular risk factors or conditions. RESULTS AND CONCLUSIONS: The patient developed intermittent episodes of fever lasting more than two months starting 3 weeks from hospital discharge, and he was never referred to the hospital by his general practitioner, until he was evaluated by his Surgeon, admitted to the Emergency Department and diagnosed with infectious endocarditis, later dying for cardiac arrest before getting a cardiac valve replacement. This report aims to be a reminder of how invasive procedures can trigger secondary distant complications that should be taken into account while assessing a post-operative patient.

OBJETIVO: La resección transuretral de próstata es el gold estándar en el tratamiento de la hiperplasia benigna de próstata. Una bacteriemia que comporta endocarditis infecciosa (EI) puede ser como resultado de procedimientos urológicos. La EI post RTU próstata es rara. METODOS: Describimos un caso inusual de endocarditis infecciosa complicada post RTU de próstata por hiperplasia benigna de próstata en ausencia de factores de riesgo cardiovascular conocidos u otras patológicas. RESULTADOS Y CONCLUSIONES: El paciente desarrolló episodios intermitentes de fiebre por más de 2 meses iniciándose a las 3 semanas del alta hospitalaria. El paciente nunca fué mandado al hospital por el medico de familia hasta que fue evaluado por su cirujano, ingresado en el servicio de urgencias y diagnosticado de endocarditis infecciosa. Finalmente murió de parada cardiorespiratoria antes de someterse a cirugía de sustitución valvular. Este caso pretende recordar lo invasivo que es el procedimiento y que puede desencadenar complicaciones secundarias que deben tenerse en consideración en el contexto postoperatorio del paciente.

T1 Bladder Cancer: Comparison of the Prognostic Impact of Two Substaging Systems on Disease Recurrence and Progression and Suggestion of a Novel Nomogram.

Background: The T1 substaging of bladder cancer (BCa) potentially impacts disease progression. The objective of the study was to compare the prognostic accuracy of two substaging systems on the recurrence and progression of primary pathologic T1 (pT1) BCa and to test a nomogram based on pT1 substaging for predicting recurrence-free survival (RFS) and progression-free survival (PFS). Methods: The medical records of 204 patients affected by pT1 BCa were retrospectively reviewed. Substaging was defined according to the depth of lamina propria invasion in T1a-c and the extension of the lamina propria invasion to T1-microinvasive (T1m) or T1-extensive (T1e). Uni- and multivariable Cox regression models evaluated the independent variables correlated with recurrence and progression. The predictive accuracies of the two substaging systems were compared by Harrell's C index. Multivariate Cox regression models for the RFS and PFS were also depicted by a nomogram. Results: The 5-year RFS was 47.5% with a significant difference between T1c and T1a (p = 0.02) and between T1e and T1m (p < 0.001). The 5-year PFS was 75.9% with a significant difference between T1c and T1a (p = 0.011) and between T1e and T1m (p < 0.001). Model T1m-e showed a higher predictive power than T1a-c for predicting RFS and PFS. In the univariate and multivariate model subcategory T1e, the diameter, location, and number of tumors were confirmed as factors influencing recurrence and progression after adjusting for the other variables. The nomogram incorporating the T1m-e model showed a satisfactory agreement between model predictions at 5 years and actual observations. Conclusions: Substaging is significantly associated with RFS and PFS for patients affected by T1 BCa and should be included in innovative prognostic nomograms.
