Systemic inflammatory response syndrome after flexible ureteroscopic lithotripsy: a study of risk factors.

OBJECTIVE: To evaluate the risk factors for systemic inflammatory response syndrome (SIRS) after flexible ureteroscopic lithotripsy (FUL). MATERIALS AND METHODS: Patients who underwent FUL between October 2012 and November 2013 were studied. Complete data was available for 260 adult patients who met this criteria. Preoperative and intraoperative risk factors that potentially contribute to SIRS were compared in patients who developed postoperative SIRS and those who did not. Furthermore, multivariable logistic regression analysis was performed and the odds ratio (OR) and 95% confidence interval (CI) were calculated to identify the independent risk factors for SIRS after FUL. RESULTS: The incidence of SIRS after FUL was 8.1%. In the univariate test analysis, significant correlation between SIRS and four factors was noted: sex of the patient (P<0.001), stone size (P=0.001), irrigation flow rate (P<0.001), and irrigation volume (P<0.001). Multivariable logistic regression analysis identified stone size (OR=1.691; 95% CI,0.879-3.255), small-caliber ureteral access sheath (UAS) (OR=2.293; 95% CI, 0.730-7.200), irrigation flow rate (OR=1.161; 95% CI, 1.096-1.230), and struvite calculi (OR=3.331; 95% CI, 0.971-11.426) as independent risk factors for SIRS after FUL. CONCLUSIONS: We recommend that the length of lithotripsy be well controlled in patients with large stone burden and struvite calculi. Staging procedures are also required. Additionally, irrigating with a low flow rate and low pressure and using a large-caliber UAS for better drainage are required to keep a low renal pelvic pressure during FUL procedures.

[Penile Flexiflate® Surgitek prosthesis explant and simultaneous three-component hydraulic Titan® Alpha 1 prosthesis implantation, with double incision technique in a patient with kidney and pancreas transplant]. / Espianto di protesi peniena Flexiflate® Surgitek e contemporaneo impianto di protesi tricomponente idraulica Titan® Alpha 1, con tecnica a doppia incisione in paziente con trapianto di rene e pancreas.

INTRODUCTION AND OBJECTIVES: We treated a 45 years old patient, suffering from diabetes mellitus since childhood, with retinal, neurovascular and kidney complications. In 1988, for erectile dysfunction (ED) resistant to medical injective treatment, the patient underwent ligation of the dorsal vein of the penis without any result. In 1989 a Flexiflate® hydraulic prosthesis was implanted with resolution of ED. In 2005 the patient underwent simultaneous kidney and pancreas transplant with a trans-laparotomic approach for end stage renal disease and diabetes mellitus. In 2009, because of the Flexiflate® Surgitek malfunction, the patient underwent explantation of the Flexiflate® prosthesis and simultaneous implantation of a Titan® Alpha 1 prosthesis with a double surgical approach. MATERIAL AND METHODS: After a peno-scrotal incision and the explant of the Flexiflate® Surgitek, a Titan® Alpha 1 prosthesis was implanted with a double incision technique. The placement of two inflatable cylinders and the pump was performed by peno-scrotal approach. Instead, the prosthesis' reservoir was placed with a separate infra-pubic incision to avoid possible injury from a single trans-inguinal approach, due to the previous laparotomy. RESULTS: After follow-up at 9 months and 1 year the prosthesis was working well and the patient satisfied. CONCLUSIONS: We couldn't find any related paper in the literature and as far as we know this is the only report on a simultaneous explant/implant of penile prosthesis with a double surgical approach in a patient with kidney and pancreas transplant.

[Treatment of severe post-prostatectomy stress urinary incontinence using AdVance sling]. / Trattamento dell'incontinenza urinaria post-prostatectomia di grado severo mediante l'uso di sling tipo AdVance.

Severe stress urinary incontinence (SUI) is usually treated by the implant of artificial sphincter positioned around bulbar urethra. AdVance sling is a functional, non-obstructive, anti-incontinence device that showed good results especially for mild and moderate SUI. We present our experience with AdVance sling in 7 patients with severe SUI unfit for artificial sphincter. Our results, after a follow-up of more than 6 months, showed a continence rate of 28% and an improvement rate of 43%, while 2 patients did not show any benefit. The success of AdVance sling depends on the integrity of urethral sphincter and can be applied also in selected cases for the treatment of severe post-prostatectomy stress urinary incontinence.
