Urodynamics in patients prior to renal transplantation

This article focuses on urodynamic evaluation (UDN) as a part of the pre-transplant assessment in a subset of patients preparing for kidney transplantation. In patients with end-stage renal disease, kidney transplantation is a preferred treatment method, offering significant improvement in quality of life and reduction in morbidity and mortality compared to long-term dialysis. Functional evaluation of the urinary tract is an essential component of the pre-transplant examination, and in indicated cases, UDN provides a comprehensive assessment of lower urinary tract function. This work highlights the importance of UDN in identifying and treating pre-existing urological problems that could impact success of the transplant and function of the donor kidney. UDN can reveal various abnormalities, such as low bladder compliance, sphincter dyssynergia, detrusor overactivity, and high filling pressures. Furthermore, the article describes specific urological situations in the pre-transplant evaluation, including the significance of fluoroscopic examination and video urodynamics in identifying anatomical and functional abnormalities in patients with neurogenic bladder and other urological diagnoses. In conclusion, the article emphasizes the importance of a comprehensive pre-transplant urological examination in identifying and appropriately managing urological comorbidities, thereby enhancing the safety and success of kidney transplantation.
