Anatomical endoscopic enucleation of the prostate: The next gold standard? Yes!

Andrologia 2020 May 13:e13643. Epub 2020 May 13.

Cambridge University Hospitals NHS Foundation Trust, Cambridge, UK.

Anatomical endoscopic enucleation of the prostate (AEEP) differs from other surgical techniques for benign prostatic obstruction (BPO) in that it removes the entire benign prostatic hyperplasia (BPH) component of the prostate. We summarise the main advantages of AEEP compared to other surgical techniques for BPO. These include better urodynamic relief of bladder outlet obstruction, superior outcomes for urinary retention even in the presence of impaired detrusor contractility, safe and effective for any size prostate, and superior durability compared to vaporisation and resection techniques.

Lasers in Transurethral Enucleation of the Prostate-Do We Really Need Them.

J Clin Med 2020 May 10;9(5). Epub 2020 May 10.

Department of Urology, Spital Thurgau AG, Frauenfeld, 8569 Münsterlingen, Switzerland.

The acronym EEP, coding for transurethral Endoscopic Enucleation of the Prostate, was introduced in 2016 by the European Association of Urology (EAU) guidelines panel on management of non-neurogenic male lower urinary tract symptoms (LUTS) and benign prostatic obstruction (BPO). Since then, a laser-based treatment, Holmium Laser Enucleation of the Prostate (HoLEP), and the current-based treatment of bipolar enucleation of the prostate (BipoLEP) are equally appreciated as valuable options for the management of benign prostatic obstruction (BPO). This was mainly inspired by the results of two meta-analyses on randomized controlled trials, comparing open prostatectomy with either Holmium Laser Enucleation of the Prostate (HoLEP) or bipolar enucleation of the prostate (BipoLEP).

Nephrotoxicity in cancer treatment: An overview.

World J Clin Oncol 2020 Apr;11(4):190-204

Instituto Multidisciplinar em Saúde, Universidade Federal da Bahia, Vitória da Conquista 45029094, Bahia, Brazil.

Anticancer drug nephrotoxicity is an important and increasing adverse drug event that limits the efficacy of cancer treatment. The kidney is an important elimination pathway for many antineoplastic drugs and their metabolites, which occurs by glomerular filtration and tubular secretion. Chemotherapeutic agents, both conventional cytotoxic agents and molecularly targeted agents, can affect any segment of the nephron including its microvasculature, leading to many clinical manifestations such as proteinuria, hypertension, electrolyte disturbances, glomerulopathy, acute and chronic interstitial nephritis, acute kidney injury and at times chronic kidney disease.

Kidney parenchyma and collecting system arise from two different embryologic units as a result of a close interaction between them. Therefore, their congenital abnormalities are classified together under the same heading named CAKUT (congenital abnormalities of the kidney and urinary tract). The pathogenesis of CAKUT is thought to be multifactorial. Read More

Pyonephrosis by and coinfection and secondary peritonitis in an obstructive uropathy patient: A case report and review of the literature.

J Family Med Prim Care 2020 Feb 28;9(2):1263-1265. Epub 2020 Feb 28.

Department of Surgery, AIIMS Bhopal, Madhya Pradesh, India.

Pyonephrosis is an uncommon condition that is associated with suppurative destruction of the renal parenchyma. Upper urinary tract obstruction by renal stones plays an important role in its aetiology. The majority of pyonephrosis is reported to be caused by aerobic bacteria but the role of anaerobes, especially black-pigmented gram-negative anaerobes, namely, Prevotella and Porphyromonas in renal infections, remain poorly defined.

Internal ureteral stents have become an integral part of urologic practice to relieve intrinsic as well as extrinsic upper urinary tract obstruction. Missed internal ureteral stents is a serious potential complication that is associated with increased patient morbidity and is especially a problem in developing countries due to poor patient compliance, lack of understanding, and poor administration of stent registry. Diagnosis of forgotten ureteral stents is usually straight forward on usual imaging. Read More
