Testosterone Replacement Therapy Is Associated with an Increased Risk of Urolithiasis
World Journal of Urology (2019) 37:2737–2746 https://doi.org/10.1007/s00345-019-02726-6 ORIGINAL ARTICLE Testosterone replacement therapy is associated with an increased risk of urolithiasis Tyler R.

Methods We conducted a population-based matched cohort study utilizing data sourced from the Military Health System Data Repository (a large military-based database that includes benefciaries of the TRICARE program). This included men aged 40–64 years with no prior history of urolithiasis who received continuous TRT for a diagnosis of hypogonadism between 2006 and 2014. Eligible individuals were matched using both demographics and comorbidities to TRICARE enrollees who did not receive TRT. The primary outcome was 2-year absolute risk of a stone-related event, comparing men on TRT to non-TRT controls. Results There were 26,586 pairs in our cohort. Four hundred and eighty-two stone-related events were observed at 2 years in the non-TRT group versus 659 in the TRT group. Log-rank comparisons showed this to be a statistically signifcant dif- ference in events between the two groups (p < 0.0001). This diference was observed for topical (p < 0.0001) and injection (p = 0.004) therapy-type subgroups, though not for pellet (p = 0.27). -

CT urogram: a pictorial essay Abraham Noorbakhsh1 · Lejla Aganovic1,2 · Noushin Vahdat1,2 · Soudabeh Fazeli1 · Romy Chung1 · Fiona Cassidy1,2 Published online: 18 June 2019 © This is a U.S. Government work and not under copyright protection in the US; foreign copyright protection may apply 2019 Abstract Purpose The aim of this pictorial essay is to demonstrate several cases where the diagnosis would have been difcult or impossible without the excretory phase image of CT urography. Methods A brief discussion of CT urography technique and dose reduction is followed by several cases illustrating the utility of CT urography. Results CT urography has become the primary imaging modality for evaluation of hematuria, as well as in the staging and surveillance of urinary tract malignancies. CT urography includes a non-contrast phase and contrast-enhanced nephrographic and excretory (delayed) phases. While the three phases add to the diagnostic ability of CT urography, it also adds potential patient radiation dose. Several techniques including automatic exposure control, iterative reconstruction algorithms, higher noise tolerance, and split-bolus have been successfully used to mitigate dose. The excretory phase is timed such that the excreted contrast opacifes the urinary collecting system and allows for greater detection of flling defects or other abnormali- ties. Sixteen cases illustrating the utility of excretory phase imaging are reviewed. Conclusions Excretory phase imaging of CT urography can be an essential tool for detecting and appropriately characterizing urinary tract malignancies, renal papillary and medullary abnormalities, CT radiolucent stones, congenital abnormalities, certain chronic infammatory conditions, and perinephric collections. -

POSTOPERATIVE IMAGING COMPLICATIONS OF URETEROSCOPIC MANAGEMENT OF UPPER TRACT TCC COMPLICATIONS OF URETEROSCOPIC INCISIONS CONCLUSION REFERENCES SUMMARY Ureteroscopy has progressed from cystoscopic examination of a dilated ureter in a child in 1929 and the initial use of rigid ureteroscopes in the 1980s, to its current state of small caliber semirigid and flexible instruments. In this chapter the authors review complications of ureteroscopy including those associated with incisional techniques where one would anticipate a higher incidence of complications. They review the his- tory and development of modern ureteroscopes, focusing on engineering advances. Clinical points made include proper patient selection and preparation; proper use of dilators, wires, and ureteral access sheaths; and the incidence, identification, and man- agement of complications associated with ureterorenoscopy (both intraopertively and postoperatively).

A small laser fiber is then used to break the stone into small pieces that are then extracted or flushed out. In most cases, to ensure that the kidney drains urine well after surgery, a ureteral stent is left in place. Ureteroscopy can also be performed for stones located within the kidney. Similar to ureteral stones, kidney stones can be fragmented and removed with baskets. Occasionally, a kidney stone will fragment with a laser into very small pieces (grains of sand), too small to be basketed. A stent is usually left in place to allow these pieces to clear over time. Ureteral Stenting: Almost always after ureteroscopy, a ureteral stent will be placed. This is a thin, hollow, plastic tube that is used temporarily to keep the ureter open and facilitates drainage of urine down to the bladder until it heals. It also allows the urine to drain and any small stone fragments to pass freely. -
Pyelography in Infants
Arch Dis Child: first published as 10.1136/adc.9.50.119 on 1 April 1934. Downloaded from PYELOGRAPHY IN INFANTS BY W. E. UNDERWOOD, F.R.C.S., Chief Assistant to a Surgical Unit, St. Bartholomew's Hospital. Pyelography in infants is an examination which is essential under certain circumstances, and from it valuable facts may often be obtained which would be undiscovered without this specialized form of investigation. Hitherto the examination has been surrounded by difficulties of such a nature that it is often unsuccessful and the child is submitted to discomfort without result. The object of this paper is to bring forward certain notes on cases where pyelography has been indicated. The observations from a series of sixteen cases have led to the development of a method whereby good pyelograms have been obtained with certainty. Instrumental pyelography in infancy is a procedure not to be advised lightheartedly, but there are occasions where the indications are definite and adequate: in these cases the anticipation of possible information to be gained justifies submitting the infants to what constitutes a major examination. In this series are cases of urinary infection resistant to the usual medical treatment, of renal pain, of renal calculi, and cases of congenital malformation http://adc.bmj.com/ of the urinary tract similar to those described by Poynton and Sheldon'. The term pyelography is used here for brevity rather than accuracy, for it embraces a complete investigation of the urinary tract, including ureterography.

Stuart Wolf, Jr., MD,1 and Khurshid R. Ghani, MBChB, MS1 Abstract Introduction: Flexible ureteroscopy (fURS) is increasingly used in the treatment of renal stones. However, wide variations exist in technique, use, and indications. To better inform our knowledge about the contemporary state of fURS for treating renal stones, we conducted a survey of endourologists worldwide. Methods: An anonymous online questionnaire assessing fURS treatment of renal stones, consisting of 36 items, was sent to members of the Endourology Society in October 2014. Responses were collected through the SurveyMonkey system over a 3-month period. Results: Questionnaires were answered by 414 surgeons from 44 countries (response rate 20.7%). U.S. surgeons accounted for 34.4% of all respondents. fURS was routinely performed in 80.0% of institutions, with 40.0% of surgeons performing >100 cases/year. Respondents considered fURS to be first-line therapy for patients with renal stones <2 cm and lower pole calculi. A substantial minority (11.3%) preferred fURS as a primary treatment modality for renal stones >2 cm. Basket displacement for lower pole stones was routinely performed by 55.8%. -

Ureteroscopy
Ureteroscopy What is a Ureteroscopy? A ureteroscopy is a “minimally invasive” procedure. This means that a urologist inserts a tube-like device with a light and a lens for viewing (ureteroscope) through the urethra (natural urinary channel) instead of making cuts. Urologists use this procedure to treat kidney stones as well as stones located in the ureter (the tube that carries urine from the kidney to the bladder.) Urologists can also use this procedure to treat patients who must remain on anticoagulation therapy. What happens during the procedure? The urologist inserts the thin ureteroscope upstream through the urethra. The ureteroscope helps deliver shock waves to the stone if necessary. No incisions are made. Once the urologist identifies the stone they break it up and remove it. It is typically an outpatient procedure meaning you go home the same day. The urologist performs it in the operating room with general anesthesia (medicine to produce loss of feeling and deep sleep) or spinal anesthesia (medication to produce loss of feeling in part of the spine) What steps should I take to prepare for the procedure? 1. Do not eat any solid food (including gum, hard candy or mints) after 12am (midnight) the night before surgery. Department of Urology - 1 - 2. Do not drink any milk products after 12am (midnight). You may drink water only and any routine medications up to 4 hours before your surgery. 3. Wear loose, simple clothing which can easily be changed. Leave all jewelry and valuables at home. 4. Bring along to the hospital a responsible adult companion who will: remain in the hospital, be available to hospital personnel during your procedure, and assist you upon discharge by driving you home with close observation of your condition. -
HAVING a URETERIC STENT What to Expect and How to Manage
You have been sent home with HAVING A URETERIC STENT What to expect and how to manage 1 INTRODUCTION In patients who have, or might have an obstruction (blockage) of the kidney, an internal drainage tube called a “stent” is commonly placed in the ureter, the tube between the kidney and the bladder. This is placed there in order to prevent of temporarily relieve the obstruction. This information sheet has been given to you to help answer some of the questions you may have about having a ureteric stent inserted. If you have any questions or concerns, please, do not hesitate to speak to a doctor or a nurse caring for you. 2 THE URINARY SYSTEM AND URETERIC STENT THE URINARY SYSTEM AND THE URETER The kidneys produce urine. Normally there are two kidneys situated in the upper part of the abdomen, towards the back. The urine formed in the kidney is carried to the bladder by a fine muscular tube called a ureter. The urinary bladder acts as a reservoir for the urine and when it is full it is emptied via the urethra. Figure 1: The urinary system HOW DOES A KIDNEY BECOME OBSTRUCTED ? Common causes of obstruction of the kidneys and ureter are: -A kidney stone or its fragments moving into the ureter, either spontaneously, or occasionally following such treatment as shock wave therapy. -Narrrowing (stricture) of the ureter anywhere along its path. This can be due. scaring of wall of the ureter, narrowing of the area where the ureter leaves from the kidney (pelvi-ueteric junction) 3 -Temporarily, following an operation or after an instrument has been inserted into the ureter and kidneys.
