“…In conventional cystography, radio-opaque dyes ( i.e. , X-ray contrast agents) are transuretherally injected through urinary catheters, and then fluoroscopic X-ray bladder images can be acquired [ 1 , 2 ]. However, this modality is ionizing and not sensitive.…”

Conventional X-ray-based cystography uses radio-opaque materials, but this method uses harmful ionizing radiation and is not sensitive. In this study, we demonstrate nonionizing and noninvasive photoacoustic (PA) and fluorescence (FL) cystography using clinically relevant indocyanine green (ICG) in vivo. After transurethral injection of ICG into rats through a catheter, their bladders were photoacoustically and fluorescently visualized. A deeply positioned bladder below the skin surface (i.e., ∼1.5–5 mm) was clearly visible in the PA and FL image using a laser pulse energy of less than 2 mJ/cm2 (1/15 of the safety limit). Then, the in vivo imaging results were validated through in situ studies. Our results suggest that dual modal cystography can provide a nonionizing and noninvasive imaging tool for bladder mapping.

“…Postoperative VUA leakage is one of the most bothersome complications of radical prostatectomy. Although it usually heals spontaneously after prolonged catheterization it may result in a poor anastomosis healing, urethral contracture, urinoma, and abscess formation [ 7 , 8 , 9 , 16 ]. The reported vesicourethral anastomosis leakage rate after laparoscopic radical prostatectomy was between 0.80 and 17% of cases [ 7 , 17 ].…”

IntroductionCreation of a watertight vesicourethral anastomosis is a challenging and time-consuming procedure. In an attempt to simplify this critical step of radical prostatectomy we have developed a laparoscopic running single suture technique and presented preliminary results previously. Here we report our two-year experience with the Chlosta's single running suture technique.Material and methodsBetween January 2013 and June 2014, 60 consecutive patients underwent laparoscopic radical prostatectomy with a running vesicourethral anastomosis using our modified technique for clinically localized prostate cancer. Analyses of the patients’ data from a prospectively maintained database with respect to perioperative characteristics, morbidity and urinary continence was performed.ResultsThe mean anastomotic time was 10.2 min. There was no clinically significant anastomotic leakage observed. Only 3 patients developed perioperative morbidity, but none of them was classified as major. Bladder neck contracture occurred in only one man and it was managed endoscopically. Overall continence rates at 3, 6, 12, and 18 months were 73%, 85%, 96.7%, and 95%, respectively, and 76.8%, 89.3%, 96.4%, and 96.4%, respectively when analysis was limited to those without adjuvant radiotherapy.ConclusionsObtained results confirm our initial observation from the preliminary report and support the use of our single running suture for the vesicourethral anastomosis in LRP.

“…They demonstrated that transrectal ultrasonography with or without contrast-enhanced ultrasound is a reliable tool for evaluating the vesicourethral anastomosis. Han et al showed that computed tomographic cystography is more accurate than conventional cystography in diagnosing urine leakage at the vesicourethral anastomosis [23].…”
