INTRODUCTION: Urinary tract regeneration using tissue engineering is one of the most challenging issues in the field of reconstructive urology. Cells seeded on scaffold are exposed to urine immediately after the implantation. The outcome of urinary bladder regeneration is depended on the ability of these cells to survive, proliferate and regenerate. The aim of this study was to compare a sensitivity of three different cell lines to urine in vitro. MATERIAL AND METHODS: Three different cell lines were isolated from porcine bladder (urothelial cells, UCs and smooth muscle cells, SMCs) and adipose tissue (adipose-derived stem cells, ADSCs)...

PURPOSE: The need for mechanical inpatient bowel preparation (IBP) in reconstructive pediatric urology has come under scrutiny, secondary to literature demonstrating little benefit regarding outcomes. Starting in 2013, a majority of patients undergoing reconstructive procedures at our institution no longer underwent IBP. We hypothesized that outpatient bowel preparation (OBP) would reduce length of stay (LOS) without increasing postoperative complications after appendicovesicostomy surgery...

The clinical application of platelet-rich plasma (PRP) is based on the increase in the concentration of growth factors that are released from alpha-granule of the concentrated platelets and in the secretion of proteins which are able to capitalize on the healing process at the cellular level. It has been invented to restore the natural beauty by starting the natural rejuvenation process of the skin and aiming to make it function as a younger one and to keep the skin youthful and maintain it. Besides that, it is also emerged to include hairs as a new injectable procedure to enable stimulating hair growth locally and topically; preventing its fall; improving hair shaft, hair stem, and its caliber; increasing its shine, vitality, and pliability; and declining hair splitting and breakage...

Stress plays a role in the exacerbation and possibly the development of functional lower urinary tract disorders. Chronic water avoidance stress (WAS) in rodents is a model with high construct and face validity to bladder hypersensitive syndromes, such as interstitial cystitis/bladder pain syndrome (IC/BPS), characterized by urinary frequency and bladder hyperalgesia and heightened stress responsiveness. Given the overlap of the brain circuits involved in stress, anxiety, and micturition, we evaluated the effects chronic stress has on bladder function, as well as its effects on regional brain activation during bladder filling...

Autologous gastrointestinal tissue has remained the gold-standard reconstructive biomaterial in urology for >100 years. Mucus-secreting epithelium is associated with lifelong metabolic and neuromechanical complications when implanted into the urinary tract. Therefore, the availability of biocompatible tissue-engineered biomaterials such as extracellular matrix (ECM) scaffolds may provide an attractive alternative for urologists. ECMs are decellularised, biodegradable membranes that have shown promise for repairing defective urinary tract segments in vitro and in vivo by inducing a host-derived tissue remodelling response after implantation...

OBJECTIVES: Normal urinary bladder stores urine at low pressure, does not leak, and completely empties by natural voiding. An abnormal bladder may be due to neurologic or urologic disorders that render the bladder of small capacity, of high storage pressure, or of poor compliance. The aim of this study was to determine the long-term outcomes of renal transplant in patients with abnormal bladders. MATERIALS AND METHODS: We retrospectively compared 30 transplanted kidneys in 25 patients with abnormal bladders with a control group comprising 30 grafts transplanted simultaneously during the same period of time (1990-2014) in 30 patients without bladder abnormality...

Our research group has reconstructed why the board certified urologists Werner Forssmann (1904-1979) and Charles Huggins (1901-1997) received the Nobel Prize in physiology or medicine (1956, and 1966, respectively). But the history of "Urology and the Nobel Prize" is in fact more multifaceted than the success stories of these two laureates suggest. James Israel (1848-1926), Berlin, Félix Guyon (1831-1920), Paris, Peter J. Freyer (1852-1921), London and Edwin Beer (1876-1938), New York were nominated for the award during the first three decades of the 20th century...

INTRODUCTION: The most important prognostic factor for oncological outcome of rectal cancer is radical surgical resection. In patients with locally advanced T4 rectal cancer (LARC) or locally recurrent rectal cancer (LRRC) (partial) resection of the urinary tract is frequently required to achieve radical resection. The psoas bladder hitch (PBH) technique is the first choice for reconstruction of the ureter after partial resection and this bladder-preserving technique should not influence the oncological outcome...

Indication has led ureteroscopy to be a worldwide technique, with the expected appearance of multiple complications. The ureteral avulsion is an uncommon severe urological complication of ureteroscopy (URS). Surgery in patients with a total ureteral loss is a demanding challenge for urologist. It requires usually immediate open or laparoscopic intervention. This case report was to present the treatment modality after ureteral avulsion. We have presented a case of 58-year-old male patient who underwent a successful repair of an upper ureteral injury...

Patient-reported outcomes and quality of life assessments are essential to studying conditions such as neurogenic bladder in which multiple management strategies are approximately equally efficacious. Innovations for the treatment of neurogenic bladder need to be guided by both clinical and patient-reported outcomes that are rigorously tested via high-quality prospective cohort or randomized studies. Collaborative research groups in reconstructive urology are critical to the study of uncommon disease processes because they allow studies to be powered adequately, foster innovative treatment strategies through collaboration, and help moderate the risk of investigator and or institutional biases...

INTRODUCTION: We aimed to determine how renal tumour scoring systems, such as RENAL, PADUA, and Centrality (C)-index, compare to clinical judgement at predicting time required for tumour removal and kidney reconstruction during partial nephrectomy. METHODS: A consecutive cohort of partial nephrectomy patients treated at The Ottawa Hospital, a tertiary care uro-oncological centre, was retrospectively reviewed. Preoperative axial images were reviewed by four experienced urological oncologists who independently rated the complexity of a partial nephrectomy from 1-10 to generate a clinical judgement score...
