Conservative other reasons.2,3 The best treatment of a ureteric stone is frequently management, with the addition of alpha blockers to facilitate conservative (nonoperative), because all interventions (even the more passage of lower ureteric stones, should be attempted in modern ones) carry risks. However, intervention may be indicated in cases of uncomplicated renal colic. Septic patients require urgent drainage and antibiotics. Other indications for referral certain situations. -
Partial Nephrectomy for Renal Cancer: Part I
REVIEW ARTICLE Partial nephrectomy for renal cancer: Part I BJUIBJU INTERNATIONAL Paul Russo Department of Surgery, Urology Service, and Weill Medical College, Cornell University, Memorial Sloan Kettering Cancer Center, New York, NY, USA INTRODUCTION The Problem of Kidney Cancer Kidney Cancer Is The Third Most Common Genitourinary Tumour With 57 760 New Cases And 12 980 Deaths Expected In 2009 [1]. There Are Currently Two Distinct Groups Of Patients With Kidney Cancer. The First Consists Of The Symptomatic, Large, Locally Advanced Tumours Often Presenting With Regional Adenopathy, Adrenal Invasion, And Extension Into The Renal Vein Or Inferior Vena Cava. Despite Radical Nephrectomy (Rn) In Conjunction With Regional Lymphadenectomy And Adrenalectomy, Progression To Distant Metastasis And Death From Disease Occurs In ≈30% Of These Patients. For Patients Presenting With Isolated Metastatic Disease, Metastasectomy In Carefully Selected Patients Has Been Associated With Long-term Survival [2]. For Patients With Diffuse Metastatic Disease And An Acceptable Performance Status, Cytoreductive Nephrectomy Might Add Several Additional Months Of Survival, As Opposed To Cytokine Therapy Alone, And Prepare Patients For Integrated Treatment, Now In Neoadjuvant And Adjuvant Clinical Trials, With The New Multitargeted Tyrosine Kinase Inhibitors (Sunitinib, Sorafenib) And Mtor Inhibitors (Temsirolimus, Everolimus) [3,4]. The second groups of patients with kidney overall survival.

The History of Lithotomy and Lithotrity
THE HISTORY OF LITHOTOMY AND LITHOTRITY Arnott Demonstration delivered at the Royal College of Surgeons of England on 24th January 1967 by Sir Eric Riches, M.C., M.S., F.R.C.S. Honorary Curator of Historical Surgical Instruments JAMES MONCRIEFF ARNOTT, who endowed these demonstrations in 1850 during the year of his first Presidency of the College, was elected to the staff of the Middlesex Hospital in 1831, and was one of the founders of its Medical School in 1835. He was chief amongst those who insisted on an eight-day holiday for medical students from Christmas Day to New Year's Day inclusive. An early advocate of the need for specialization in surgery, he undertook in 1843 the duty of running an ophthalmological out-patient clinic in addition to his general surgery. He was a strict disciplinarian but had a dry sense of humour. It was recorded that on a teaching round, after showing a newly invented instrument most completely fitted for the desired purpose, he ended by saying, ' In fact, gentlemen, it is one of those ingenious conceptions which is of no use.' There are many ingenious conceptions in the collection of Historical Surgical Instruments in this College; some are now ' of no use', but many are the precursors of modern instruments and serve as historical landmarks in the development of surgical technique. In no branch is this more evident than in the surgery of stone in the bladder and it seems appropriate to base this account of the history of the operations devised for it on the instruments used. -

Urogenital System Surgery Urogenital System Anatomy
UROGENITAL SYSTEM SURGERY UROGENITAL SYSTEM ANATOMY Kidneys and Ureters Urinary Bladder Urethra Genital Organs Male Genital Organs Female KIDNEY and URETHERS The kidneys lie in the retroperitoneal space lateral to the aorta and the caudal vena cava. They have a fibrous capsule and are held in position by subperitoneal connective tissue. The renal pelvis is the funnel shaped structure that receives urine and directs it into the ureter. Generally, five or six diverticula curve outward from the renal pelvis. The renal artery normally bifurcates into dorsal and ventral branches; however, variations in the renal arteries and veins are common. The ureter begins at the renal pelvis and enters the dorsal surface of the bladder obliquely by means of two slit like orifices. The blood supply to the ureter is provided from the cranial ureteral artery (from the renal artery) and the caudal ureteral artery (from the prostatic or vaginal artery). Urinary bladder and urethra The bladder is divided into the trigone, which connects it to the urethra, and the body. The urethra in male dogs and cats is divided into prostatic, membranous (pelvic), and penile portions. Surgery of Kidney and Urethers Nephrectomy is excision of the kidney; nephrotomy is a surgical incision into the kidney. Pyelolithotomy is an incision into the renal pelvis and proximal ureter; a ureterotomy is an incision into the ureter; both are generally used to remove calculi. Neoureterostomy is a surgical procedure performed to correct intramural ectopic ureters; ureteroneocystostomy involves implantation of a resected ureter into the bladder. Nephrotomy to obtain tissue samples or to gain access to the renal pelvis for removal of nephroliths or other obstructive lesions. -
Methods of Urolith Removal
3 CE CE Article CREDITS Methods of Urolith Removal Cathy Langston, DVM, DACVIM (Small Animal Internal Medicine) Kelly Gisselman, DVM Douglas Palma, DVM John McCue, DVM Animal Medical Center New York, New York Abstract: Multiple techniques exist to remove uroliths from each section of the urinary tract. Minimally invasive methods for removing lower urinary tract stones include voiding urohydropropulsion, retrograde urohydropropulsion followed by dissolution or removal, catheter retrieval, cystoscopic removal, and cystoscopy-assisted laser lithotripsy and surgery. Laparoscopic cysto- tomy is less invasive than surgical cystotomy. Extracorporeal shock wave lithotripsy can be used for nephroliths and ureteroliths. Nephrotomy, pyelotomy, or urethrotomy may be recommended in certain situations. This article discusses each technique and gives guidance for selecting the most appropriate technique for an individual patient. ew, minimally invasive techniques for removing preventive measures.7 Surgical removal of partial or com- uroliths have been developed or have become more pletely obstructing ureteroliths that do not pass within 24 Nreadily available in veterinary medicine.

Approaches to Pyelolithotomy
Vet Times The website for the veterinary profession https://www.vettimes.co.uk APPROACHES TO PYELOLITHOTOMY Author : Nitzan Kroter Categories : Vets Date : February 14, 2011 Nitzan Kroter discusses this procedure in reference to a case involving the removal of calcium phosphate renoliths in a cat with only one functional kidney Summary A 12-year-old cat was presented for chronic weight loss. Clinical evaluation and investigation revealed an atrophied left kidney with nephroliths and an enlarged right kidney containing multiple renal calculi. Bilateral calcium phosphate renal calculi were diagnosed. This report describes pyelolithotomy in a cat. Pyelolithotomy was performed to avoid damage to the renal parenchyma, which could occur during a nephrotomy, and, therefore, minimise further damage to an already compromised kidney. Before performing surgery, consideration of the patient’s renal function is important to obtain optimal results. Maintaining normal urine production in the pre-operative and postoperative period is important in all cases. Pyelolithotomy in the dog is covered and described in the literature; the author is unaware of a detailed description of pyelolithotomy in a cat. Key words kidney, pyelolithotomy, urine 1 / 7 A NEUTERED domestic shorthaired male feline presented with a complaint of marked weight loss over the preceding few months. It weighed 2.6kg. When recorded two-and-ahalf years previously, its weight had been 5.5kg. The owner reported recent increased activity, the cat was more talkative and attention seeking, and had a normal appetite. There was no history of polydipsia or polyuria, and there had been no vomiting or diarrhoea. Clinical examination and investigation The patient had a body condition score of 2/4 and an unkempt coat, but it was responsive and alert. -
New Alternatives for Minimally Invasive Management of Uroliths: Nephroliths
3 CE Credits New Alternatives for Minimally Invasive Management of Uroliths: Nephroliths Alice Defarges, DVM, DACVIM University of Guelph Allyson Berent, DVM, DACVIM The Animal Medical Center New York, New York Marilyn Dunn, DMV, DACVIM Université de Montreal Abstract: Urolithiasis is a common clinical problem in small animal veterinary patients. Management of upper urinary tract calculi can be particularly challenging in small animals, as traditional surgical removal can be associated with significant morbidity. In humans, minimally invasive treatment options have replaced traditional surgical removal in many cases. This article reviews the current literature on the various types of lithotripsy and some of the newer minimally invasive options available for management of nephrolithiasis in small animal veterinary patients. An article in the January 2013 issue addressed management of lower urinary tract uroliths; a future article will discuss current management strategies for ureteroliths. For more information, please see the companion article: Nephrolithiasis “New Alternatives for Minimally Invasive Management of Uroliths: Many canine and feline nephroliths remain static in size and Lower Urinary Tract Uroliths” (January 2013). clinically silent for years.

Urinary Bladder – Calculus Urinary Bladder – Crystal
Urinary bladder – Calculus Urinary bladder – Crystal Figure Legend: Figure 1 A calculus (asterisk) fills the entire bladder lumen in a male F344/N rat from a chronic study. Figure 2 Hyperplasia of the urothelium (arrow) due to the presence of the calculus in a male F344/N rat from a chronic study. Figure 3 A small basophilic calculus (arrow) associated with chronic inflammation and urothelial hyperplasia in a female Harlan Sprague-Dawley rat from a chronic study. Comment: Calculi may be seen as spontaneous or as chemically induced lesions. Calculi may be single or multiple (Figure 1). Gross examination of the bladder is important since some small calculi may be washed out of the bladder when processed for histopathology. Calculi result from the precipitation of normal constituents or chemical compounds/metabolites associated with changes in urinary pH or other conditions. Frequently in the rodent, calculi contain some form of 1 Urinary bladder – Calculus Urinary bladder – Crystal calcium or mineral complex. Calculi often result in necrosis, ulceration, inflammation, and hyperplasia of the urothelium (Figure 2 and Figure 3). They are often the cause of bladder obstruction. In addition, bladder neoplasia may result from the presence of calculi. The presence of crystals and the subsequent appearance of calculi are often associated. Strain differences in the presence of crystals have been reported. Crystals, like calculi, tend to be washed out during histologic processing. Recommendation: Calculi and crystals should be diagnosed but should not be graded. Calculi are usually associated with secondary lesions, such as hemorrhage and inflammation. The pathologist should use his or her judgment in deciding whether or not these secondary lesions are prominent enough to warrant a separate diagnosis.
