The lifetime incidence of kidney stones is approximately 13 percent for men and 7 percent for women.1,2 Reports conflict regarding whether incidence is rising overall but consistently report rising incidence in women and a falling male-to-female ratio.3-5 Although stones may be asymptomatic,6 potential consequences include abdominal and flank pain, nausea and vomiting, urinary tract obstruction...

IMPORTANCE Kidney stone disease is common and may be associated with an increased risk of coronary heart disease (CHD). Previous studies of the association between kidney stones and CHD have often not controlled for important risk factors, and the results have been inconsistent. OBJECTIVE To examine the association between a history of kidney stones and the risk of CHD in 3 large prospective ...

BACKGROUND Percutaneous nephrolithotomy (PCNL) is recommended for treating staghorn stones or stones measuring > 20 mm. Extracorporeal shockwave lithotripsy (ESWL) or flexible ureteroscopy (URS) may be used as a complement. However, PCNL can cause trauma to the kidney parenchyma, and patients may find a noninvasive procedure, such as ESWL, to be more attractive. OBJECTIVES The aim of this stu...

BACKGROUND Extracorporeal Shock Wave Lithotripsy (ESWL) is a non-invasive treatment of urinary stones which breaks them, by using externally applied, focused, high intensity acoustic pulse, into smaller pieces so that they can pass easily through ureter. Shock wave generation, focusing, coupling and stone localisation by fluoroscope or ultrasound are the basic components of ESWL. ESWL has some ...

A 67-year-old male presented with left kidney stones in renal pelvis, 15 mm length. Preoperative CT showed massive splenomegaly. Retrograde intrarenal surgery approach was decided to avoid splenic injury, achieving the absence of residual stones.

The prevalence of kidney stone disease is increasing worldwide with significant health and economic burden. Newer research is finding that stones are associated with several serious morbidities. Yet, few randomized clinical trials or high quality observational studies have assessed whether clinical interventions decrease the recurrence of kidney stones. Therefore, in this review we analyze the ...

Dual-energy computed tomography (DECT) has recently been suggested as the imaging modality of choice for kidney stones due to its ability to provide information on stone composition. Standard postprocessing of the dual-energy images accurately identifies uric acid stones, but not other types. Cystine stones can be identified from DECT images when analyzed with advanced postprocessing. This case...

The use of extracorporeal shockwave lithotripsy (ESWL) to treat kidney stones gives excellent fragmentation results. However, the retention of post-ESWL fragments within the kidney remains a serious health problem. A study carried out on calcium stone patients showed that only 32% of these were found to be stone free 12 months after ESWL [1]. Therefore, the persistence and the growth of fragmen...

In the present study, the clinical effects of flexible ureteroscopy lithotripsy (FURL) and percutaneous nephrolithotomy (PCNL) for the treatment of kidney stones of ≤2 cm was studied. Seventy-two patients with kidney stones were randomly divided into the FURL group (n=39) under ureteroscope lithotripsy with holmium laser and PCNL group (n=33) under PCNL with holmium laser and compared their cli...

I am greatly honoured to be invited to give the Scott-Heron Lecture for 1983 but feel very inadequate to follow the distinguished doctors who have preceded me. The interest in the kidney was first aroused by a young woman with bilateral staghorn calculi, while working as a house surgeon with the late Mr. Cecil Woodside. Mr. Woodside was a general surgeon who had a special interest in the kidney...
