Pneumatic retinopexy for retinal detachment occurring after prior scleral buckle or pars plana vitrectomy.

BACKGROUND AND OBJECTIVE: To report outcomes of pneumatic retinopexy (PR) for retinal detachment (RD) occurring after prior scleral buckling surgery (SB) or pars plana vitrectomy (PPV). PATIENTS AND METHODS: Single-center study evaluating all patients treated between January 2000 and March 2013. RESULTS: Ten eyes underwent PR after prior SB. Nine of these 10 eyes had persistent subretinal fluid posterior to the buckle in the setting of an open break on the scleral buckle. The mean time to PR in these cases was 8.5 days after SB. PR achieved anatomic reattachment in eight of 10 eyes, but two of 10 eyes required additional PPV to achieve retinal reattachment. Seven eyes underwent PR after prior PPV. The average time to RD after PPV was 67 days (range: 15-232 days). The location of the break was superior in four eyes, horizontal in two, and inferior in one. Anatomic reattachment with PR alone occurred in four of seven eyes (57%). CONCLUSION: In the setting of recurrent RD after initial SB, pneumatic retinopexy was usually successful in the early postoperative course. In the setting of a new-onset RD after PPV, pneumatic retinopexy was a useful option, but recurrent RD was more common.

A noninvasive bladder sensory test supports a role for dysmenorrhea increasing bladder noxious mechanosensitivity.

OBJECTIVE: Catheterization to measure bladder sensitivity is aversive and hinders human participation in visceral sensory research. Therefore, we sought to characterize the reliability of sonographically estimated female bladder sensory thresholds. To demonstrate this technique's usefulness, we examined the effects of self-reported dysmenorrhea on bladder pain thresholds. METHODS: Bladder sensory threshold volumes were determined during provoked natural diuresis in 49 healthy women (mean age, 24±8 y) using 3-dimensional ultrasound. Cystometric thresholds (Vfs, first sensation; Vfu, first urge; Vmt, maximum tolerance) were quantified and related to bladder urgency and pain. We estimated the reliability (1-wk retest and interrater). Self-reported menstrual pain was examined in relationship to bladder pain, urgency, and volume thresholds. RESULTS: Average bladder sensory thresholds (mL) were Vfs (160±100), Vfu (310±130), and Vmt (500±180). Interrater reliability ranged from 0.97 to 0.99. One-week retest reliability was Vmt=0.76 (95% CI, 0.64-0.88), Vfs=0.62 (95% CI, 0.44-0.80), and Vfu=0.63 (95% CI, 0.47-0.80). Bladder filling rate correlated with all thresholds (r=0.53 to 0.64, P<0.0001). Women with moderate to severe dysmenorrhea pain had increased bladder pain and urgency at Vfs and increased pain at Vfu (P's<0.05). In contrast, dysmenorrhea pain was unrelated to bladder capacity. DISCUSSION: Sonographic estimates of bladder sensory thresholds were reproducible and reliable. In these healthy volunteers, dysmenorrhea was associated with increased bladder pain and urgency during filling but unrelated to capacity. Plausibly, women with dysmenorrhea may exhibit enhanced visceral mechanosensitivity, increasing their risk to develop chronic bladder pain syndromes.
