ation incur a high risk of anatomic recurrence within 1 year and such patients may warrant increased monitoring. High submuscular (HSM) placement of inflatable penile prosthesis (IPP) reservoirs is a promising new FDA approved alternative to traditional space of Retzius reservoir placement. In 2011, we began placing all reservoirs in a HSM position at our tertiary center. In 2014, we proposed a refined, "Five-Step" HSM reservoir placement technique (FST) to prevent deep pelvic complications. To describe our HSM technique and report on our extended experience. Our refined FST was developed to optimize outcomes and includes the following steps (1) Position and Access; (2) Develop Lower HSM Pocket; (3) Develop Upper HSM Pocket; (4) Reservoir Delivery (Fill and Fine-Tune); (5) Confirm and Connect. Data was retrospectively collected on patients undergoing reservoir placement by FST between January 2014 and June 2019. A survey analyzing subjective outcomes and patient satisfaction was performed among 100 randomly selected patients. We placed 297 consecutive HSM IPP reservoirs via FST during this time period. Three patients (1.0%) required surgical revision (all for herniation). No deep pelvic (vascular, bladder, bowel) complications were reported. Of the 100 patients that were randomly surveyed, 86% of patients reported no palpability of the reservoir, and 95% of patients reported satisfaction with the procedure and would recommend the procedure to a friend. The FST for HSM reservoir placement is a simple and safe procedure with good outcomes and excellent patient satisfaction. This technique appears to effectively eliminate the risks of deep pelvic complications.

To guide management of preoperative hydronephrosis prior to radical cystectomy (RC), we compared post-RC risks of upper tract urothelial carcinoma (UTUC) and ureteroenteric anastomotic complications between ureteral stent and percutaneous nephrostomy tube drainage. Patients who underwent RC for urothelial carcinoma without a prior diagnosis of UTUC at our institution between 2000 and 2015 were included and divided into 4 patient groups (1) no hydronephrosis (75%, N=787); (2) hydronephrosis without preoperative upper tract drainage (13%, N=132); (3) hydronephrosis treated with nephrostomy tube (3%, N=36); (4) hydronephrosis treated with ureteral stent (9%, N=94). The incidence of post-RC UTUC and ureteral complications was compared using Kaplan-Meier analyses and multivariable Cox proportional hazard modeling. We identified a total of 1049 patients who underwent RC (median postoperative follow-up 4.3 years). Five-year post-RC UTUC incidence was 6.6%, 10.2%, 17%, 18.7% for groups 1-4, respectively (P= .13n for UTUC risk. To assess the histologic findings in the pubic bone resected during extirpative surgery for urinary pubic symphysis fistula (UPF). The concurrent presence of osteomyelitis and the need for bone resection at time of extirpative surgery for UPF has been debated. We hypothesized that UPF results in histopathologically confirmed osteomyelitis, underscoring the importance of bone resection at the time of surgery. An IRB-approved retrospective review of all patients undergoing surgery for UPF from 2012 to 2019 was performed. Demographic data were recorded. A single pathologist performed histopathologic examination of bone tissue in each case. Logistic regression and Fisher exact test were used to assess association of osteomyelitis with clinical factors. We identified 36 patients who underwent major extirpative surgery for UPF with bone pathology available for review. Bone histopathology findings confirmed presence of osteomyelitis in the majority (n = 32, 88.9%). This was characterized as chronic osteomyelitis in 15 (41.7%), acute osteomyelitis only in 1 (2.8%) and combined chronic, and acute osteomyelitis in 16 (44.4%). Osteonecrosis was seen in 11 cases (33.6%). There was no correlation between presence of osteomyelitis and age, timing from radiotherapy to diagnosis of UPF, type of radiotherapy, or history of endoscopic bladder outlet procedures. Osteomyelitis is present on histology of the pubic bone resected during surgery for UPF in the majority of cases (88.9%). Osteonecrosis is also common. These findings underscore the critical importance of pubic bone resection at time of UPF surgery to adequately treat the diseased bone.

Flaviviral non-structural protein 3 (NS3) protease-helicase plays essential roles in viral replication and is an attractive antiviral target. A construct which connects the cytoplasmic cofactor region of NS2B and NS3 protease with an artificial glycine-rich flexible linker has been widely used for structural, biochemical and drug-screening studies. The effect of this linker on the dynamics and enzymatic activity of the protease has been studied by several biochemical and NMR methods but the findings remained inconclusive. Here, we designed and carried out a comparative study of constructs of NS2B cofactor joined to the full length DENV4 NS3 in three different ways, namely bNS2B47NS3 (bivalent), eNS2B47NS3(enzymatically cleavable) and gNS2B47NS3 (glycine-rich linker). We report the crystal structures of linked and unlinked NS2B47-NS3 constructs in their free state and in complex with bovine pancreatic trypsin inhibitor (BPTI). These structures demonstrate that the NS2B cofactor predominantly adopts a closed conformation in complex with full-length NS3. The glycine-rich linker between NS2B and NS3 may promote the open conformation which interferes with protease activity. This negative impact on the enzyme structure and function is restricted to the protease activity as the ATPase activity is not affected in vitro.
