Laparoscopic nephron-sparing surgery for a tumor near the isthmus of a horseshoe kidney with a complicated blood supply.

J Int Med Res 2020 Jun;48(6):300060520926736

Department of Urology, the Fourth Medical Center of PLA General Hospital, Beijing, China.

A horseshoe kidney is a congenital kidney malformation commonly associated with complications such as hydronephrosis, renal calculi, and infections of the renal pelvis. Renal cell carcinoma is extremely rare in a horseshoe kidney; once it occurs, however, it is intractable because of vascular abnormalities. This is especially true in laparoscopic nephron-sparing surgery, even for tumors of <4 cm in diameter. Read More

SEM-EDX linear scanning: a new tool for morpho-compositional analysis of growth bands in urinary stones.

J Biol Inorg Chem 2020 Jun 2. Epub 2020 Jun 2.

BioCruces Sanitary Research Institute, Cruces University Hospital, Barakaldo, Spain.

The genesis and growth of calculi are imprinted in their structure, so the pathogenesis of lithiasis could potentially be read via proper analytical techniques. In this study, electron microscopy with energy-dispersive X-ray spectroscopy (SEM-EDX) is used to obtain a description of the morphology and compositional structure of a single bladder stone. This technique establishes the chemical and crystalline architecture of the urolith to assess the effect of the chemical environment on its growth. Read More

Andrology Laboratory, Department of Urology, West China Hospital, Sichuan University, Chengdu 610041, P.R.China.

Recently, artificial intelligence (AI) has been widely applied in the diagnosis and treatment of urinary diseases with the development of data storage, image processing, pattern recognition and machine learning technologies. Based on the massive biomedical big data of imaging and histopathology, many urinary system diseases (such as urinary tumor, urological calculi, urinary infection, voiding dysfunction and erectile dysfunction) will be diagnosed more accurately and will be treated more individualizedly. However, most of the current AI diagnosis and treatment are in the pre-clinical research stage, and there are still some difficulties in the wide application of AI. Read More

Percutaneous nephrolithotomy for staghorn calculi: Troubleshooting and managing complications.

Asian J Urol 2020 Apr 19;7(2):139-148. Epub 2019 Oct 19.

Department of Urology, University of California, Oakland, CA, USA.

Staghorn calculi comprise a unique subset of complex kidney stone disease. Percutaneous nephrolithotomy (PCNL) is the gold standard treatment for staghorn stones. Despite continuous refinements to the technique and instrumentation of PCNL, these stones remain a troublesome challenge for endourologists and are associated with a higher rate of perioperative complications than that for non-staghorn stones.

Contemporary role of multi-tract percutaneous nephrolithotomy in the treatment of complex renal calculi.

Asian J Urol 2020 Apr 28;7(2):102-109. Epub 2019 Dec 28.

Department of Urology, Muljhibhai Patel Urological Hospital, Nadiad, Gujarat, India.

Complex renal calculi remain to be a challenge for the treating urologist due to sheer bulk and the technicalities involved. Percutaneous nephrolithotomy (PCNL) remains the treatment modality of choice in dealing with these large and complex stones. The limiting factor in their treatment continues to be the need for using additional tracts or the use of flexible nephroscopy for complete stone clearance. Read More

Multitract percutaneous nephrolithotomy in staghorn calculus.

Asian J Urol 2020 Apr 8;7(2):94-101. Epub 2019 Oct 8.

Department of Urology, Muljibhai Patel Urological Hospital, Nadiad, India.

Staghorn calculi are branched stones which occupy a majority portion of the pelvicaliceal system. An untreated staghorn calculus over time can damage the kidney and deteriorate its function and/or cause life threatening sepsis. Total stone clearance is an important goal in order to eradicate any infective focus, relieve obstruction, prevent recurrence and preserve the kidney function. Read More

Department of Urology, Wake Forest University Baptist Medical Center, Winston-Salem, NC, USA.

Objective: Staghorn calculi present a particular and challenging entity of stone morphology. Treatment is associated with lower stone-free rates and higher complication rates compared to non-staghorn stones. In this review we looked for the most relevant data on preoperative imaging and access planning to help decision making for percutaneous surgery with this complex condition. Read More

Morphometry scores: Clinical implications in the management of staghorn calculi.

Asian J Urol 2020 Apr 12;7(2):78-86. Epub 2019 Jun 12.

Department of Urology, Icahn School of Medicine at Mount Sinai, New York, NY, USA.

Due to their large size, rapid growth, and attendant morbidity, staghorn calculi are complex clinical entities that impose significant treatment-related challenges. Moreover, their relative heterogeneity-in terms of both total stone burden and anatomic distribution-limits the ability to standardize their characterization and the reporting of surgical outcomes. Several morphometry systems currently exist to define the volumetric distribution of renal stones, in general, and to predict the outcomes of percutaneous nephrolithotomy; however, they fall short in their applicability to staghorn stones.

Stevan B, Streem Center for Endourology & Stone Disease, Glickman Urological & Kidney Institute, The Cleveland Clinic, Cleveland, OH, USA.

Patients with staghorn renal stones are challenging cases, requiring careful preoperative evaluation and close follow-up to avoid stone recurrence. In this article we aim to discuss the main topics related to staghorn renal stones with focus on surgical approach. Most of staghorn renal stones are composed of struvite (magnesium ammonium phosphate) and are linked to urinary tract infection by urease-producing pathogens. Read More

Atma Jaya Catholic University of Indonesia, Jakarta, Indonesia.

Duplication of ureter is one of the most common anomalies of the urinary tract. Early detection has dramatically increased due to advance in technology of imaging to detect the anomalies during antenatal period; however, numbers of undiagnosed adult still exist. It may remain asymptomatic, but may cause repeated urinary tract infections or calculi. Read More

Heartlands, Good Hope, and Solihull Hospitals, University Hospitals Birmingham NHS Foundation Trust, Birmingham, United Kingdom.

Objectives: Computed tomography scans of the kidney, ureters, and bladder (CT-KUB) are crucial in investigating urinary calculi but impart a substantial radiation doses. Radiation can be limited by minimising the scanning field to the necessary area ( from the kidneys to urethra). Before auditing, the superior limit of CT-KUB scans had not been formally clarified at our trust. Read More
