Review of the Current Management of Upper Urinary Tract Injuries by the EAU Trauma Guidelines Panel

CONTEXT The most recent European Association of Urology (EAU) guidelines on urological trauma were published in 2014. OBJECTIVE To present a summary of the 2014 version of the EAU guidelines on upper urinary tract injuries with the emphasis upon diagnosis and treatment. EVIDENCE ACQUISITION The EAU trauma guidelines panel reviewed literature by a Medline search on upper urinary tract injuries; publication dates up to December 2013 were accepted. The focus was on newer publications and reviews, although older key references could be included. EVIDENCE SYNTHESIS A full version of the guidelines is available in print and online. Blunt trauma is the main cause of renal injuries. The preferred diagnostic modality of renal trauma is computed tomography (CT) scan. Conservative management is the best approach in stable patients. Angiography and selective embolisation are the first-line treatments. Surgical exploration is primarily for the control of haemorrhage (which may necessitate nephrectomy) and renal salvage. Urinary extravasation is managed with endourologic or percutaneous techniques. Complications may require additional imaging or interventions. Follow-up is focused on renal function and blood pressure. Penetrating trauma is the main cause of noniatrogenic ureteral injuries. The diagnosis is often made by CT scanning or at laparotomy, and the mainstay of treatment is open repair. The type of repair depends upon the severity and location of the injury. CONCLUSIONS Renal injuries are best managed conservatively or with minimally invasive techniques. Preservation of renal units is feasible in most cases. This review, performed by the EAU trauma guidelines panel, summarises the current management of upper urinary tract injuries. PATIENT SUMMARY Patients with trauma benefit from being accurately diagnosed and treated appropriately, according to the nature and severity of their injury.

Utility and limitations of 3-Tesla diffusion-weighted magnetic resonance imaging for differentiation of renal tumors

OBJECTIVE To investigate utility and limitations of 3-Tesla diffusion-weighted (DW) magnetic resonance imaging (MRI) for differentiation of benign versus malignant renal lesions and renal cell carcinoma (RCC) subtypes. MATERIALS AND METHODS Sixty patients with 71 renal lesions underwent 3 Tesla DW-MRI of the kidney before diagnostic tissue confirmation. The images were retrospectively evaluated blinded to histology. Single-shot echo-planar imaging was used as the DW imaging technique. Apparent diffusion coefficient (ADC) values were measured and compared with histopathological characteristics. RESULTS There were 54 malignant and 17 benign lesions, 46 lesions being small renal masses ≤ 4 cm. Papillary RCC lesions had lower ADC values (p=0.029) than other RCC subtypes (clear cell or chromophobe). Diagnostic accuracy of DW-MRI for differentiation of papillary from non-papillary RCC was 70.3% resulting in a sensitivity and specificity of 64.3% (95% CI, 35.1-87.2) and 77.1 (95% CI, 59.9-89.6%). Accuracy increased to 83.7% in small renal masses (≤ 4 cm diameter) and sensitivity and specificity were 75.0% and 88.5%, respectively. The ADC values did not differ significantly between benign and malignant renal lesions (p=0.45). CONCLUSIONS DW-MRI seems to distinguish between papillary and other subtypes of RCCs especially in small renal masses but could not differentiate between benign and malignant renal lesions. Therefore, the use of DW-MRI for preoperative differentiation of renal lesions is limited.

Postureteroscopic Lesion Scale: A New Management Modified Organ Injury Scale—Evaluation in 435 Ureteroscopic Patients

BACKGROUND AND PURPOSE Objective parameters for the classification of ureteral injuries and resulting indications for ureteral stent placement after ureteroscopy are lacking. We hereby present a new classification system including proof of interrater reliability and validation of recommendations for postoperative ureteral stent placement. PATIENTS AND METHODS The Postureteroscopic Lesion Scale (PULS) was applied in 435 patients undergoing ureteroscopy. Interrater reliability between three surgeons (junior resident, senior resident, and specialist) was evaluated in 112 patients. Postoperative ureteral stent placement was performed according to PULS. For follow-up with ultrasonography, we assumed hydronephrosis to be an indirect sign for significant postoperative ureteral obstruction. RESULTS No ureteral lesion was seen in 46.2% of patients (grade 0). A grade 1, 2, or 3 lesion was seen in 30.8%, 19.1%, and 3.9% of patients, respectively. No grade 4 or 5 lesions were observed in our series. Interrater reliability was high (Kendall W=0.91; mean Spearman Rho=0.86). This was particularly true between senior resident and specialist (Rho=0.95), compared with junior resident and senior resident or specialist (Rho=0.83, Rho=0.79, respectively). All patients with documented lesions had a Double-J stent placed. Indwelling time varied according to PULS. Results of a postoperative ultrasonographic follow-up could be obtained in 95.6% of cases. No patient showed clinical or sonographic signs of upper urinary tract obstruction. CONCLUSIONS According to these preliminary data for the clinical application of PULS, interrater reliability is high. Standardized empiric recommendations for the use and duration of postoperative stent placement after ureteroscopy might be useful in guiding urologists in this conversely discussed issue, ultimately preventing ureteral strictures as a late complication of ureteroscopy. These will have to be confirmed, however, by controlled trials in the future.

Penile lengthening and widening without grafting according to a modified 'sliding' technique.

Modified Sliding Technique (MoST) for Penile Lengthening with Insertion of Inflatable Penile Prosthesis

Indication Penile curvature caused by Peyronie’s disease (PD) and the subsequent difficulty with penetration and shortened stretched penile length are extremely distressing to men. Although plication may work for low magnitude simple curvature, plaque manipulation and grafting has been the preferred method for correcting large or complex deformities. Penile plication leads to “long side” penile shortening, whereas grafting may lead to erectile dysfunction. We describe the Modified Sliding Technique (MoST) for correcting PD combined with penile lengthening with neurovascular bundle (NVB) and urethral mobilization followed by inflatable penile implant placement, using a single sub-coronal incision.

Multidetector computed tomography virtual cystoscopy: an effective diagnostic tool in patients with hematuria.

OBJECTIVE To evaluate the efficacy and the potential use of multidetector computed tomography virtual cystoscopy (MDCT-VC) in patients with gross hematuria. METHODS A total of 32 patients underwent MDCT-VC, cystoscopy, and a cytologic examination. The slice thickness of MDCT was 1 mm. Bladder distension was done with room air. The data were converted into 3-dimensional virtual reconstructive models. The data sets were reviewed independently by 2 experienced radiologists. Tumors confined to the mucosa, infiltrating the muscularis, and transmural tumors were distinguished. RESULTS VC showed a sensitivity and specificity of 100%. The radiologic accuracy regarding T stage correlated in 87.5%. MDCT-VC identified 21 bladder lesions suspicious for bladder cancer in 18 patients. The histologic results showed 22 patients with bladder lesions, 18 were diagnosed with transitional cell carcinoma of the bladder, 3 had bladder endometriosis, and 1 had an infiltrating colon cancer. Four patients had concomitant carcinoma in situ lesions, which were not seen completely with MDCT-VC. However, cytology was positive in those cases. Ten patients did not have any tumor signs on VC and the subsequent conventional cystoscopy did not bring any change to the initial tumor-free diagnosis of VC. CONCLUSION MDCT-VC combined with urine cytology is a good alternative to conventional cystoscopy for patients with painless gross hematuria. It should be used as a decision-making aid to identify patients who will benefit from additional cystoscopic examination. Future developments should focus on the visibility of sessile and carcinoma in situ lesions.
