Antiphospholipid syndrome (APS) is a systemic disorder clinically characterized by widespread thrombosis and obstetric complications associated with the persistent presence of antiphospholipid antibodies (aPLs). The persistent presence of aPLs represents a thrombotic risk in APS, which can be stratified according to the aPL profile. Thrombosis occurs in both arteries and veins. PD98059 Notably, arterial thromboses have a higher recurrence compared with venous thromboses and a tendency for recurrence in the same vascular (arterial) site. Secondary prevention of arterial thrombosis requires more intensive treatment than prevention of venous thrombosis. Data from randomized clinical trials indicated that factor Xa inhibitors should not be recommended for APS. Recurrent thromboses in patients with APS treated with factor Xa inhibitors were mainly arterial, with a high rate of stroke. Dual antiplatelet therapy may have some benefit for preventing the recurrence of arterial thrombosis in patients with APS. This review article describes pathogenic mechanisms, clinical features, risk assessment, and management of arterial thrombosis in patients with APS. Particularly, we discuss how secondary prophylaxis may be a useful approach to reduce the occurrence of arterial thrombosis.To date, scleroderma renal crisis (SRC) remains a life-threatening complication in patients affected by systemic sclerosis (SSc), with high morbidity and mortality. In the last few years, some studies have tried to more precisely identify predictors of SRC and clarify the role of previous drug exposure-in particular, angiotensin-converting enzyme (ACE) inhibitors and corticosteroids-in patients with SSc presenting other well-known risk factors for SRC. Different from the findings of previous reports, more recent findings suggest that the presence of chronic kidney disease, systemic arterial hypertension, and proteinuria might all be predictors of SRC. Moreover, because about 40 to 50% of SRC cases can present signs of microangiopathy, a recent study has proposed SSc thrombotic microangiopathy (SSc-TMA) as a clinically and pathophysiologically different entity from narrowly defined SRC. Even though such clear distinction may not always be applicable/feasible in clinical practice, it highlights that complement pathway dysregulation may play a key pathogenetic role in SRC presenting as TMA. Thus, plasma exchange may be considered in severe refractory cases. Nevertheless, ACE inhibitors and prompt achievement of blood pressure control (to rapidly improve ongoing renal ischemia) remain to date the cornerstone of SRC treatment. Here, we report the cases of three SSc patients with SRC followed at our rheumatology units. While describing these patients' risk factors, clinical presentation, and therapy, we aim to discuss the state of the art in SRC and highlight critical issues.
In this study, we aimed to present the perioperative and postoperative outcomes and early continence rates of the first 50 patients who underwent Retzius-sparing robot-assisted laparoscopic radical prostatectomy (RS-RALP) in our clinic for prostate adenocarcinoma.

Between December 2018 and December 2019, 50 patients who underwent RS-RALP by 2 surgeons in our clinic were enrolled in the study. Preoperative, perioperative, and postoperative clinical data were analyzed retrospectively. Procedure-specific complications were graded according to the Clavien-Dindo classification. The continence status of the patients was recorded in the 1
week, 1
month, and 3
month after catheter removal. Zero pads or 1 safety pad per day was accepted as total continence.

The mean age of the patients was 66.6 (57-75) years. According to the D'Amico classification, 36% of patients were at low risk, 48% at intermediate risk, and 16% at high risk. Bilateral or unilateral nerve-sparing procedure was performed in 76% of the patients. There were no intraoperative complications. A total of 9 (18%) patients had a postoperative complication (7 with grade 1, 1 with grade 2, and 1 with grade 3 complications). Whereas 32% of the patients had an extraprostatic extension, 22% had seminal vesicle invasion. The overall positive surgical margin rate was 26%. At 1 week, 1 month, and 3 months after surgery, 64%, 80%, and 92% of men who underwent RS-RALP were continent, respectively.

Our study showed that this new surgical technique can be a safe and feasible method because high rates of early continence were achieved in the patients who underwent RS-RALP without increasing the risk of complications.

Surgical treatment for female urethral stricture is varied and lacks consensus. Dorsal and ventral approaches of urethroplasty have comparable success rate with debatable limitations. We describe modifications in dorsal onlay graft urethroplasty to mitigate the surgical limitations and improve functional outcomes.

We retrospectively analyzed 8 patients with strictures treated with dorsal onlay urethroplasty at our center. The inclusion criteria were American Urology Association (AUA) score >20, calibration <14 Fr, positive voiding cystourethrogram, urodynamics with maximum urine flow rate (Qmax) <12 mL/s, detrusor pressure at maximum flow >24 cmH
O, and urethroscopic visualization of the stricture. Surgical modifications included dorsal plane dissection away from the clitoris; limited lateral urethral dissection; omitting graft quilting onto the clitoris, and urethral slitting directly at the stricture site (for mid and proximal strictures), sparing the meatus and using canoe-shaped grafts for distal strictures. Success was defined as improvement in the AUA scores and Qmax >12 mL/s, without requiring any further intervention.

The mean age was 50.5±10.6 years. Statistically significant improvements in mean AUA score [14.5±2.20 (p=0.012)], Qmax [23.63±2.44 (p=0.012)], post-void residual urine [107.88±40.37 (p=0.012)], and sexual function scores [6.833±2.23 (p=0.027)] were noted at a mean follow-up of 3 months. Distal strictures were more common. Mean urethral caliber was 9.62 Fr. No cases of de novo incontinence or sexual dissatisfaction were reported.

In our experience, the dorsal onlay technique works well, but without a comparative evidence for ventral onlay, it is difficult to conclude that one is preferred over the other.
