Miniaturized percutaneous Nephrolithotomy without antibiotic prophylaxis: a single institution experience.

PURPOSE: To assess the feasibility of sparing routine antibiotic prophylaxis in patients without preoperative urinary tract infection (UTI) undergoing a miniaturized percutaneous nephrolithotomy (mPCNL). PATIENTS AND METHODS: A retrospective, monocentric study was conducted to evaluate the outcome of a modified perioperative antibiotic management strategy according to the principles of antibiotic stewardship (ABS). From December 2015 patients undergoing mPCNL for kidney stone with preoperative unremarkable urine culture no longer received an antibiotic prophylaxis (NoPAP). The NoPAP group was compared to mPCNL patients who received standard antibiotic prophylaxis (PAP) in the two years before. Analysis focused on postoperative complications. Logistic regression analysis was performed to identify potential risk factors. RESULTS: Postoperative fever occurred in 8% of the NoPAP and 9% of the PAP patients (p = 0.764). Clavien 1-3 complications did not differ between groups with 33% in the NoPAP and 41% in the PAP (p = 0.511). No Clavien 4-5 complications were seen. A (partial) staghorn stone (HR 5.587; p = 0.019) and an infectious stone component (HR 6.313; p = 0.003) were identified as significant risk factors for postoperative fever. By sparing routine antibiotic prophylaxis the overall antibiotic usage was reduced from 100% (PAP) to 9% (NoPAP). CONCLUSION: Patients with negative preoperative UC, a none-staghorn stone and no history of recurrent UTI or infectious stones may not need routine antibiotic prophylaxis prior to mPCNL. A prospective validation is warranted.

Long-term outcome after grafting with small intestinal submucosa and collagen fleece in patients with Peyronie's disease: a matched pair analysis.

Advanced Peyronie's disease (PD) with severe penile curvature requires grafting following plaque incision or partial plaque excision. So far, the ideal graft material has not been identified although various grafts have been studied. In this first matched pair analysis we compared the outcome after grafting with small intestinal submucosa (SIS) and self-adhesive collagen fleece (CF). We retrospectively identified 43 patients after SIS grafting with complete follow-up data sets to be eligible for the present study. A total of 43 patients after CF grafting were matched case by case to the SIS group using the degree of preoperative penile curvature as the primary matching factor. Postoperative outcome was compared with the focus on penile straightening, penile length, potency, relapse rates and long-term complications. Median degree of curvature was 80° in each group. Mean follow-up periods were 31 months after SIS and 39 months after CF grafting. The CF grafting procedure was significantly faster than SIS grafting (80 vs. 104 min, p < 0.001). No major short-term complications were observed. Both techniques gained good long-term penile straightening rates. Relapse of penile curvature was observed after SIS grafting only. Postoperative penile shortening occurred more often after SIS grafting (28% vs. 5%, p = 0.007). With a mean preoperative IIEF-5 score of 16, the SIS cohort significantly differed from the CF cohort with a mean IIEF-5 score of 19 (p = 0.016). The median IIEF-5 score improvement was higher after SIS grafting (+4.5 vs. +1, p = 0.002). Diminished penile sensation was the main long-term side effect with low rates after both procedures (9% and 7% in the SIS and CF group respectively, p = 0.100). In this first matched pair analysis both techniques showed promising long-term results. CF seems to have advantages regarding duration of surgery and preserving penile length. More comparative studies with larger collectives are desirable.

Bicentric prospective evaluation of corporoplasty with porcine small intestinal submucosa (SIS) in patients with severe Peyronie's disease.

INTRODUCTION: Advanced Peyronie's disease (PD) with severe penile deviation demands grafting procedures following plaque incision or partial plaque excision in order to avoid penile shortening and to improve quality of life of affected patients. Small intestinal submucosa (SIS) is an established xenograft. The objective of the present study was to validate external results in a bicentric prospective manner. METHODS: Patient selection criteria, surgical technique and standards for pre- and postoperative care were defined. Consecutively, patients with severe penile deviation in stable disease and sufficient erectile function were included between 2007 and 2015. After plaque incision, grafting was performed using SIS in a standardized manner. The postoperative evaluation using a non-validated questionnaire included complications, correction of curvature, pre- and postoperative erectile function, change in penile length and general satisfaction with the procedure. RESULTS: Forty-three patients underwent surgery between 2007 and 2015. The mean degree of preoperative curvature was 73.8° (range 60-90°). No intraoperative or major postoperative complications were reported. After a mean follow-up of 33.0 months (range 10-59), complete straightening of the penis was achieved in 74.4%. 88.4% of all patients were able to achieve satisfying sexual intercourse (67.4% unaided, 21.0% with assistance). The IIEF-5 score was improved in 69.8% (mean improvement 4.0 points). Overall 86.0% were satisfied with the surgical treatment. CONCLUSION: Corporoplasty with SIS in patients with PD and severe penile curvature is a safe approach and shows good long-term results. A thorough patient selection and a standardized pre-, intra- and postoperative procedure are decisive for a satisfying outcome.

Morpheaartige Hautmanifestation einer Sarkoidose : Morpheaform skin lesions in sarcoidosis.

Sarcoidosis is an idiopathic systemic disease, which is characterized by the presence of non-caseating granulomas in the affected organs. Cutaneous manifestations are frequently the first clue to the diagnosis; however, the clinical picture of the lesions is heterogenous. Here we report on a 66-year-old woman with localized indurations of the skin on both forearms that were diagnosed as a rare morphea-like skin involvement of a systemic sarcoidosis.
