Timothy D McClure, Daniel J A Margolis, Jim C Hu
PURPOSE OF REVIEW: The index lesion theory has created a strong interest in partial gland ablation for men with prostate cancer. By only treating the focus of clinically significant disease and avoidance of surrounding periprostatic tissue, one may provide adequate oncologic control with minimal side effects. Accurate identification of the index lesion and effective ablation are critical for satisfactory oncologic outcomes. Herein, we review key ablative techniques used in partial gland ablation...

Thomas R W Herrmann, Mathias Wolters, Mario W Kramer
PURPOSE OF REVIEW: Inherent limitations of conventional transurethral resection of bladder tumors as the standard approach for diagnosis and treatment of bladder cancer are well know: staging error because of insufficient assessment of resection depth as well as intravesical tumor fragmentation that complicates histopathological evaluation. The purpose of this review is to present recent clinical data on en bloc resection of bladder tumor (ERBT) that has been demonstrated to offer high potential to overcome these limitations...

Stephan Huusmann, Udo Nagele, Thomas R W Herrmann
PURPOSE OF REVIEW: Miniaturized percutaneous nephrolithotomy (PCNL) procedures have reached big popularity in the past years. Following the idea that decreasing the diameter of the instruments would decrease the complication rate instruments with outer diameter down to 4,8 Fr was established. In this review, we want to take a critical insight of the most popular miniaturized procedures, regarding the key advantages and disadvantages of the miniaturized instruments. RECENT FINDINGS: For all techniques displayed, a number of studies are available to support their effectivity in the given range of indication...

Esteban Emiliani, Olivier Traxer
PURPOSE OF REVIEW: Flexible ureteroscopy has been widely developed in the last decade been nowadays one of the first line treatment options for urolithiasis and conservative management for upper tract urothelial tumors. Even though some unfavorable features of the reusable flexible scopes can limit the surgical procedure such as their availability, lack of sterilization or costly repairs. Disposable scopes have been developed with the intention of improving such problems. RECENT FINDINGS: To our knowledge, seven devices have been developed...

PURPOSE OF REVIEW: Progress in imaging, fusion software, and ablative modalities has fostered growth of the latest image-guided generation of high-intensity focused ultrasound (HIFU) for focal treatment of prostate cancer. Although early reports are encouraging, important questions remain regarding candidate selection, treatment, and outcomes. We review contemporary considerations for the use of HIFU for focal treatment of primary and radio-recurrent prostate cancer. RECENT FINDINGS: HIFU has been used to treat prostate cancer for over two decades...

#7
Esmee Iml Liem, Theo M de Reijke
PURPOSE OF REVIEW: The recurrence rate in patients with nonmuscle invasive bladder cancer is high, and the quality of transurethral resection of the bladder (TURB) tumour influences recurrence risk. We review new methods that aim to improve the effectiveness of TURB, and highlight studies of the past year. RECENT FINDINGS: Several approaches have been explored: bipolar resection is well tolerated and efficient; however, surgical outcomes are not clearly superior to monopolar resection; en-bloc resection seems feasible and well tolerated, and has the potential to improve the quality of tissue for histopathology; enhancement techniques such as photodynamic diagnosis, narrow band imaging, and Image1 S improve tumour detection, whereas photodynamic diagnosis reduces recurrence rates; high-resolution imaging modality such as confocal laser endomicroscopy may provide histopathologic information...

PURPOSE OF REVIEW: To evaluate the role of prostatic inflammation in the development and progression of benign and malignant prostatic diseases. RECENT FINDINGS: Preclinical studies demonstrate that the activation of a chronic inflammatory prostatic response plays an important role in the pathogenesis and progression of benign prostatic hyperplasia (BPH) and prostate cancer (PCa). Approximately 40-70% of patients with BPH-related lower urinary tract symptoms harbour chronic inflammation at pathologic evaluation...

Tommaso Cai, Bela Koves, Truls E Bjerklund Johansen
PURPOSE OF REVIEW: Asymptomatic bacteriuria (ABU) is a common clinical condition that often leads to unnecessary treatment. The purpose of this review is to outline and evaluate the most recent literature on the management of ABU. RECENT FINDINGS: The role of ABU management has been evaluated in several patient subgroups: healthy patients without identified risk factors, pregnant women, postmenopausal women, women with recurrent UTI, patients with diabetes, elderly institutionalized patients, patients with renal transplants, patients with indwelling catheters and prior to surgery...

#10
Elisabetta Costantini, Konstantinos Giannitsas, Ester Illiano
PURPOSE OF REVIEW: To summarize evidence on the efficacy of nonantibiotic treatments in the prevention of recurrent urinary tract infections (UTIs). The need for antibiotic-free regimens seems to be imperative given the worldwide rates of resistance of uropathogens to available antibiotics. RECENT FINDINGS: In the recently published literature, cranberry products and probiotics are the focus of research. They both seem to be effective in preventing recurrent UTIs compared with placebo, but their benefit becomes less clear when they are compared with antibiotics...

Magnus J Grabe, Karl-Johan Lundström
PURPOSE OF THE REVIEW: The controversies surrounding perioperative antimicrobial prophylaxis (AMP) are about the use and especially misuse of antibiotics. The overall lack of evidence to facilitate a rational perioperative AMP policy in urological surgery and the postoperative infectious complications remain a challenge. Therefore, a basic tool to aid decision-making would be useful. A model based on the patients' risk factors, the level of contamination and grading of surgical procedures is discussed...

PURPOSE OF REVIEW: In the era of increasing antibiotic resistance worldwide, this review highlights the advantages of revival of old antibiotics for treatment of uncomplicated urinary tract infections (uUTIs). RECENT FINDINGS: Recent studies have shown that these four oral old antibiotics, fosfomycin trometamol, nitrofurantoin, nitroxoline and pivmecillinam, show no increasing antibiotic resistance against uropathogens causing uUTI, are still effective for the treatment of uUTI and exhibit only minimal or no collateral damage as compared with fluoroquinolones or third-generation cephalosporines...

Florian M E Wagenlehner, Zafer Tandogdu, Truls E Bjerklund Johansen
PURPOSE OF REVIEW: The urinary tract is the infection site in severe sepsis/septic shock in 10-30%. RECENT FINDINGS: There is a new Sepsis definition focusing on severe sepsis. Urosepsis is mainly due to obstructed uropathy of the upper urinary tract. The pathogenesis of sepsis is complex and is driven by the innate immune system. In the further course immunosuppression is developing.Management of urosepsis includes early diagnosis, early initiation of treatment such as identification and control of the complicating factor in the urinary tract and the specific sepsis therapy...

PURPOSE OF REVIEW: A specialized epithelial cell with chemosensory properties of taste cells known from the mouth has been newly identified in the urethra and linked to pathogen recognition. We here describe its properties and its link to defence mechanisms, showing parallels to similar sentinel cells in the respiratory and gastrointestinal tract. RECENT FINDINGS: In the urethra, slender epithelial cells with apical microvilli ('brush cells') express bitter and umami taste receptors and the downstream signalling cascade known from oropharyngeal gustation, utilizing it to monitor for bacterial products and bacterial growth facilitating conditions...

PURPOSE OF REVIEW: Management of genitourinary malignancy is likely to encompass a large portion of most of the urologist's practice. The challenge for the modern urologist is not only in understanding the management of commonly seen genitourinary malignancies, but also in recognizing unusual variants and their differences in management. This is evermore important as new technologies have refined the ability to identify rare entities. This review presents a brief overview of the various genitourinary malignancy subtypes seen within urology...

PURPOSE OF REVIEW: The purpose of this article was to describe the systemic therapy of genito-urinary sarcomas. RECENT FINDINGS: High rate of distant metastasis and high mortality rate has brought interest into the development of new therapeutic approaches. Various modules of chemotherapy were sampled in sarcoma treatment, although clinical response is still unsatisfactory. Chemotherapy in sarcomas can be used as neoadjuvant or adjuvant to the surgery. There is no consensus on the current role of adjuvant chemotherapy...
