“…Eggert et al [10] reported a sensitivity of 100% and specificity of 97.5% using a TRUS for assessing the urinary leakage at the VUA site on postoperative day 6 in a series of 100 men undergoing RRP. Schenck and Schneider [11] developed a new method for evaluating the VUA using a dynamic TRUS with bladder filled only with NaCl 0.9% on postoperative days 4-8. If the urine is still cloudy or bloody, dynamic TRUS would be too early because a persisting VE at the anastomosis is very likely (96.9% likelihood).…”

“…Transrectal ultrasonography (TRUS) has been proposed as an alternative tool for detecting urinary leakage at the site of VUA and it can be performed directly by the urologist in the office with no need for transferring the patient to a radiology suite [10,11]. More recently, transrectal contrast-enhanced ultrasonography (CEUS) has been shown to be another reliable tool in this setting by offering a similar performance to CG [12].…”

Objectives: To evaluate the diagnostic accuracy of cystography (CG), transrectal ultrasonography (TRUS) and transrectal contrast-enhanced ultrasonography (CEUS) for the detection of vesicourethral extravasation (VE) after radical retropubic prostatectomy (RRP). Patients and Methods: In 80 consecutive patients who underwent RRP, the strength of the vesicourethral anastomosis (VUA) was assessed by CG, TRUS and transrectal CEUS. The investigation started with a conventional CG evaluated by an experienced uroradiologist. Following this, patients underwent TRUS which was performed by an experienced urologist who was blinded to the CG findings. The examination started with a conventional B-scan and, subsequently, a CEUS was performed by emptying and refilling the bladder with 90 ml of NaCl 0.9% + 10 ml suspension of 1:10 SonoVue and NaCl 0.9%. Results: 26 patients (32.5%) presented urinary VE and 54 (67.5%) a watertight VUA. In 16 patients (61%) we observed a small leakage, 9 patients (35%) presented a moderate VE, and a large VE was detected in 1 patient (4%). No statistically significant difference in detection of VE was found among the three tests (p = 0.472). Conclusions: TRUS and CEUS are able to provide information about the integrity of the VUA that is comparable with that of CG.

“…The postoperative factors which increase the anastomotic leak are postoperative urinary tract infection [15] and pelvic para-anastomotic haematoma [15]. In addition, a bloody urine colour is a predictive factor for urethrovesical anastomotic leakage [16][17].…”

Objectives: To determine whether macroscopic hematuria predicts urethrovesical anastomotic leakage after robot-assisted laparoscopic radical prostatectomy (RALP) as well as a cystogram.Patients and methods: Participants were recruited before cystogram and catheter removal 5 to 14 days after RALP surgery. Urine colour in the collection bag was classified according to a three-step scale (clear, light red and dark red) and leakages in cystogram were graded with a four-step scale (Grade 0-3). Diagnostic accuracy parameters were calculated for urine colour. A multivariate logistic regression model was used to evaluate other leakage risk factors.Results: Of 214 patients, 201 (94%) had clear, 6 (3%) had light red and 7 (3%) had dark red coloured urine. In the cystogram, 20 (9%) patients had leakage; 14 had Grade 1, 5 Grade 2 and 1 Grade 3 leakage. Overall, specificity and sensitivity of urine colour in predicting anastomotic leakage were 0.97 (95% CI 0.95-100) and 0.38 (95% CI 0.17-0.59), respectively. Negative and positive predictive values were 94% and 62%, respectively.Other significant risk factors for anastomotic leakage were previous transurethral resection or radiation therapy to the prostate, non-waterproof anastomosis at surgery, postoperative pelvic hematoma, long catheterization and surgeon's inexperience. In patients with no other risk factors, test sensitivity improved to 0.80 (95% CI 0.45-1.15) and negative and positive predictive values to 99% and 44%, respectively. Conclusion: Our prospective single-arm trial indicates that in patients with clear urine and no other risk factors for anastomotic leakage, a cystogram examination before urethral catheter removal can be safely omitted.

“…Urine color is one of the important attributes of urinalysis, which is shown to be useful in differentiating various medical situations. 2 In ancient medical practices, as suggested by the retained manuscripts, urine examination and specifically urine color has been frequently reported as a crucial diagnostic material for a wide variety of illnesses. 3,4 An example of such ancient medical practice is traditional Persian medicine, which, despite its long history, is considered today as a new brand of complementary and alternative medicine.…”

The color of urine is an important factor in urine examination, which can help physicians differentiate various diseases. Today, it is known that certain dyes, drug intoxications, and diseases can induce green urine discoloration. In the view of traditional Persian medicine, which is based on humoral medicine, green urine discoloration is generally referred to the dominance of coldness in the body. In fact, it is considered to be a result of a special kind of humoral imbalance and fluid depletion or retention in the human body. Persian scholars believed that green urine could be an indicator of intoxication or a predictor of an imminent spasm or convulsion in pediatric patients. Further investigations could result in finding new diagnostic scales of urine color based on the teachings of traditional Persian medicine.
