Abstract Purpose: A prophylactic ureteral localization stent (PULSe) placed by urologists aids in intraoperative localization and detection of suspected ureteral injury during complex colorectal surgery (CRS) cases. We evaluated the incidence and management of urologic-induced complications secondary to PULSe placement during CRS cases at a single center. Materials and Methods: We performed a retrospective review of all patients who underwent cystoscopy and PULSe placement at the time of CRS over a 12-month period. Bilateral 5 French ×70-cm TigerTail ® (Bard Medical Division, Covington, GA) PULSe devices were placed without assistance of routine fluoroscopy. Results: Ninety-nine patients (mean age, 58.1 years; range, 17–88 years) underwent bilateral PULSe placement, with a male:female ratio of 44:55 and a mean body mass index of 26.8 (17.0–38.6) kg/m 2 . Mean pre- and postprocedural creatinine levels were 0.91 and 1.01 mg/dL, respectively. Twenty-two of 99 (22%) cases utilized a guidewire to aid in placement of PULSe. Four Clavien grade IIIb complications occurred: mucosal edema, reflex anuria, ureteral perforation, and ureteral obstruction secondary to significant clot burden. Three of the grade IIIb complications were managed endoscopically with double-J stent placement. The ureteral perforation case required percutaneous nephrostomy tube placement. Subgroup analysis of the four grade IIIb complications revealed a mean age of 62.3 years, body mass index of 26.98 kg/m 2 , and pre- and postprocedural creatinine levels of 0.95 and 4.83 mg/dL, respectively. Only one of the four grade IIIb complications utilized a guidewire prior to PULSe placement. Conclusions: The incidence of Clavien grade III urologic-induced complications during PULSe placement is approximately 2% (4/188). Mandatory adoption of fluoroscopy and guidewires may be required to minimize complications of PULSe placement.

Objectives To assess the safety and efficacy of tadalafil once daily on lower urinary tract symptoms suggestive of clinical benign prostatic hyperplasia ( BPH‐LUTS ) in men without erectile dysfunction ( ED ). To compare these with effects in men with ED . Patients and Methods After a 4‐week washout period and 4‐week placebo run‐in period, 1089 men without ED ( n = 338) and with ED ( n = 751) were randomly assigned to placebo or tadalafil 5 mg once daily for 12 weeks in three global clinical studies with similar designs. In the pooled dataset, post hoc analyses of covariance assessed the impact and severity of BPH‐LUTS using the I nternational P rostate S ymptom S core ( IPSS ) and the BPH I mpact I ndex ( BII ) and IPSS quality‐of‐life ( IPSS ‐ QoL ) subscores. Safety was assessed using treatment‐emergent adverse events. The treatment‐by‐ ED ‐status interaction was used to assess efficacy differences between the with/without ED subgroups. Results Men without ED were similar in BPH‐LUTS severity/previous therapy to men with ED . Tadalafil significantly reduced BPH‐LUTS from baseline when compared with placebo in men without ED ( IPSS −5.4 vs −3.3, P < 0.01; IPSS voiding subscore −3.5 vs −2.0, P < 0.01; IPSS storage subscore −1.9 vs −1.3, P < 0.05). Tadalafil also significantly improved quality of life from baseline when compared with placebo in men without ED ( IPSS ‐ QoL −1.0 vs −0.7, BII −1.4 vs −1.0; both P < 0.05). Between‐ ED ‐subgroup interactions were not significant (all P > 0.68). Tadalafil was safe and well tolerated. Conclusion Tadalafil 5 mg once daily improved BPH‐LUTS in men without ED by a magnitude similar to that observed in men with ED . The adverse event profile in men without ED was consistent with that observed in men with ED .

Background and Purpose— Previous studies have suggested that family members with intracranial aneurysms (IAs) often harbor IAs in similar anatomic locations. IA location is important because of its association with rupture. We tested the hypothesis that anatomic susceptibility to IA location exists using a family-based IA study. Methods— We identified all affected probands and first-degree relatives (FDRs) with a definite or probable phenotype in each family. We stratified each IA of the probands by major arterial territory and calculated each family’s proband-FDR territory concordance and overall contribution to the concordance analysis. We then matched each family unit to an unrelated family unit selected randomly with replacement and performed 1001 simulations. The median concordance proportions, odds ratios (ORs), and P values from the 1001 logistic regression analyses were used to represent the final results of the analysis. Results— There were 323 family units available for analysis, including 323 probands and 448 FDRs, with a total of 1176 IAs. IA territorial concordance was higher in the internal carotid artery (55.4% versus 45.6%; OR, 1.54 [1.04–2.27]; P =0.032), middle cerebral artery (45.8% versus 30.5%; OR, 1.99 [1.22–3.22]; P =0.006), and vertebrobasilar system (26.6% versus 11.3%; OR, 2.90 [1.05–8.24], P =0.04) distributions in the true family compared with the comparison family. Concordance was also higher when any location was considered (53.0% versus 40.7%; OR, 1.82 [1.34–2.46]; P <0.001). Conclusions— In a highly enriched sample with familial predisposition to IA development, we found that IA territorial concordance was higher when probands were compared with their own affected FDRs than with comparison FDRs, which suggests that anatomic vulnerability to IA formation exists. Future studies of IA genetics should consider stratifying cases by IA location.

Background Higher mortality for patients with aneurysmal subarachnoid haemorrhage has been reported. Aims In families with intracranial aneurysms, we sought to determine whether mortality among subjects with intracranial aneurysm (affected) was higher and related to rupture, compared with unaffected family members. Methods Subjects enrolled in the Familial Intracranial Aneurysm protocol were contacted yearly and their status was obtained. If reported to be deceased, the cause of death was verified by available records. A Cox proportional hazards model was utilized to compare mortality rates. Results Of the 2794 subjects, 1073 were affected and 1721 were unaffected. There were 8525 person-years of follow-up (mean 3·05 ± 1·73 years) and 85 deaths. Age at study entry for the affected (58·4 ±11·9 years) was significantly older ( P < 0·0001) than for the unaffected (52·2 ± 16·1). After adjusting for age, the overall mortality rate for the affected subjects was not significantly different from that for the unaffected (Rate Ratio [RR] 1·26, 95% confidence interval 0·82–1·93, P = 0·292). There was a strong effect modification due to age. The mortality rate ratio of the affected to the unaffected who were ≤60 years of age was RR = 3·48 (95% confidence interval: 1·59–7·63, P = 0·002), the rate for the affected subjects who were ≥60 was less than the rate for the unaffected (RR = 0·69, 95% confidence interval: 0·404–1·19, P = 0·178). The affected who had ruptures had 2·62 times the mortality rate as those without ruptures (95% confidence interval 1·43–4·80, P = 0·002). Conclusion The overall mortality was similar for the affected and unaffected subjects in this cohort. Among the affected only, those with ruptured intracranial aneurysm had a higher mortality rate than those without ruptured.

AbstractBackgroundCancer‐specific anxiety (CSA) can affect treatment decisions and is common in men following surgery for prostate cancer (PCa). We hypothesized that CSA is also associated with factors affecting quality of life. Herein, we examine the association of CSA with psychosocial factors and PCa aggressiveness in a cohort of men 1 year after prostatectomy for localized PCa.MethodsFrom our prospective PCa Registry, we identified 365 men who underwent prostatectomy for localized PCa who completed the Memorial Anxiety Scale for Prostate Cancer (MAX‐PC) and Expanded Prostate Cancer Index Composite at 1‐year follow‐up. We evaluated the association of scores on the MAX‐PC with demographics, clinicopathologic features, sexual function, and depression scores using Wilcoxon Rank Sum and Kendall's tau correlation tests.ResultsHigher scores on the MAX‐PC (i.e., higher anxiety) are associated with younger age (p < 0.01) and non‐Caucasian race (p < 0.01). Men with higher MAX‐PC scores also reported poor sexual satisfaction/function (p < 0.01) and increasing depressive symptoms (p < 0.01). Finally, although higher anxiety is associated with several pathologic features of aggressiveness (stage, positive margins, PSA at 1 year; all p‐values < 0.01), we noted several men with clinically indolent disease who reported significant anxiety.ConclusionsOur data suggest that higher levels of CSA are associated with poor sexual function and increased depressive symptoms 1 year after prostatectomy. Moreover, we noted demographic and pathologic features associated with higher CSA as well. If confirmed, our data support development of models to predict men at high risk of CSA following PCa surgery and targeted referral for additional counseling. Copyright © 2012 John Wiley & Sons, Ltd.
