Evolution from Percutaneous nephrolithotomy to Mini-PCNL in supine position on the treatment of complex renal calculi: feasibility study.

CONCLUSIONS: Mini-NLP can manage kidney stones and even large staghorn calculi without nephrostomy in a high percentage of patients. The technical evolution towards a small caliber approach maintains the effectiveness of the procedure without impacting its safety, with benefits perceived by patients such as less postoperative pain.

The kids were asleep, and I could hear a muted, distant moaning coming from our bedroom. It reminded me of labor pains, but there were three things making labor unlikely: my wife’s IUD, the absence of a gravid abdomen and the kind of unintentional celibacy that occurs between working parents raising two toddlers. I tried to ignore the moaning. In part, because it was a Sunday night, and the sound was disrupting the golden hour (the 60 minutes between the kid’s bedtime and my own), and because I could immediately recognize this was something potentially very bad. If I didn’t acknowledge it, perhaps, it wou...

ABSTRACT A 41-year-old male presented at Emergency Department (ED) with right flank pain associated with hematuria for 3 days. Patient had a previous history of nephrolithiasis. The physical examination and blood tests were normal. Urine analyses showed haematuria> 1.000.000/ μ L. After clinical evaluation, a computer tomography (CT) showed right ureteral dilatation caused by a 5 mm proximal stone and a distal intraluminal mass of 8 cm in length. In this setting, an ureteroscopic biopsy was performed and revealed a large polypoid lesion histologically suggestive of fibroepithelial polyp. Due to technical difficulties...

We present a 40-year-old transplanted patient, not only perirenal ossification but also with multiple perirenal stones. The presentation was severe pain on the site of transplantation. Pre-op CT scan revealed perirenal calcified mass. Intraoperative finding was verythick tissue accompanied with a lot of stones around the transplanted kidney. The patient had history of ureteral fistula after renal transplantation that needed temporary percutaneous nephrostomy and then uretero-neocystomy.It seems that urinary leakage through nephrostomy site probably is the predisposing factor for stone formation around the kidney where as t...

A 33-year-old, otherwise healthy man presented with worsening epigastric and flank pain for 3 weeks. He denied having vomiting, diarrhea, fever, urinary symptoms or history of kidney stones. His vital signs were significant for a blood pressure of 140/72 mmHg and pulse rate of 94 bpm. Acute coronary syndrome was excluded by electrocardiography. A computed tomography (CT) scan of the chest and abdomen with contrast demonstrated aneurysmal dilation of the entire length of descending thoracic and abdominal aorta with the proximal descending thoracic aorta measuring about 4.8 cm in diameter [Figure 1].

This study intended to investigate the effects of Polygonum Aviculare L. aqueous extract (PAE) on urolithiasis induced by ethylene glycol (EG) and ammonium chloride (AC) in rats. MATERIALS AND METHODS: Sixty-four male Wistar rats were randomly divided into eight groups (n = 8). Rats in the normal control group (I) received no treatment. The sham groups (III and IV) were given PAE. at 100 and400 mg/kg by gavage for 28 days. The disease control group (II), the prevention groups ( V and VI), and the therapeutic groups (VII and VIII), received 1% EG and .25 AC in their drinking water for 28 days. The prevention groups (fr...

A 67-year-old woman presented to the emergency department with a 2-day history of right-sided flank pain. A noncontrast abdominal computed tomography (CT) scan revealed a partially obstructing right ureteral calculus. Incidentally found on noncontrast CT was a 2.7-cm right-sided adrenal mass that measured 15 Hounsfield units (HU), appeared homogenous and round, had smooth borders, and did not have calcifications or necrotic areas. The patient had no prior cross-sectional imaging for comparison. She spontaneously passed the kidney stone, with resolution of her pain.

ConclusionsThe nonspecific symptoms of ureteral endometriosis can result in incorrect diagnosis, with renal damage as a result of prolonged hydronephrosis. A high index of suspicion and use of imaging modalities enable earlier diagnosis and preservation of renal function.

The objective of the present study is to derive a model for the early detection of the type of kidney stone and the most influential parameters with the aim of providing a decision-support system. Information was collected from 936 patients with nephrolithiasis at the kidney center of the Razi Hospital in Rasht from 2012 through 2016. The prepared dataset included 42 features. Data pre-processing was the first step toward extracting the relevant features. The collected data was analyzed with Weka software, and various data mining models were used to prepare a predictive model. Various data mining algorithms such as the Bay...

'Every couple of years since 2002 I would have constant bowel pain. It was a dull ache, with waves of sharp spasms, says David Calver, who benefited from new kidney stone treatment.
