Approaches to nephron-sparing surgeries (NSS) of renal lesions include partial nephrectomy (PN) and tumor enucleation (TE). Our objective was to examine the pathology of the pseudocapsule and status of the surgical margin in small renal masses treated by NSS and to correlate these findings with the surgical and oncological outcomes. All consecutive renal TE and PN specimens obtained during the period between January 2012 and December 2014, of which clinical follow-up was available, were included in this study...

Delayed sequelae following conservative management of renal trauma in the pediatric population are uncommon. Reports of delayed operations to manage these sequelae are even less common. Here we present the case of a 16-year-old male patient who had delayed development of upper urinary tract obstruction with recurrent infections following high-grade renal trauma managed conservatively. Ultimately he required a robotic-assisted partial nephrectomy two years after initial non-operative management. This is unique as no prior studies to our knowledge have described delayed hydronephrosis and delayed partial nephrectomy over a year following renal trauma...

Laparoscopic donor nephrectomy (LDN) can be performed via either transperitoneal or retroperitoneal approach. Very few studies have been carried out till now, comparing immunologic and inflammatory responses in donors after these two approaches. This is a prospective observational study. Selection of approach was decided by the operating surgeon. All patients underwent peripheral venous blood sampling preoperatively and 24 h postoperatively for the measurement of C-reactive protein (CRP), interleukein-6 (IL-6), total leukocyte count (TLC), blood urea nitrogen (BUN), and serum creatinine (SCr)...

Renal hydatid disease accounts for 2% of all cases of hydatid cysts. With the majority of isolated renal hydatid disease patients being asymptomatic, hydatid cysts grow slowly for several years. They may be associated with pressure symptoms or flank pain, depending on their size and location. Hydatiduria occurs in less than one-fifth of the patients. In the absence of hydatiduria, diagnosis is usually radiological. Surgery is the mainstay of treatment which is usually renal sparing surgery as most cysts are non-communicating...

BACKGROUND: Primary hyperparathyroidism (PHPT) is a common endocrine disorder. Beside renal and skeletal complications, it has a wide variety of nonspecific symptoms from other organs that mimic other diseases and delay the diagnosis. In recent decades the clinical profile of PHPT has evolved to less symptomatic forms. OBJECTIVES: The aim of the study was to revise the symptomatology profile of PHPT in a single region, and to facilitate early PHPT diagnosis by encouraging interdisciplinary communication among medical professionals...

INTRODUCTION: Postoperative pain management in living kidney donor nephrectomy plays a key role in donor comfort and is important for the further acceptance of living kidney donation in times of organ shortage. Standard pain treatment (SPT) based on opioids is limited due to related side effects. Continuous infusion of local anesthesia (CILA) into the operative field is a promising alternative. The aim of this study was to evaluate whether CILA could reduce the dose of opioids in living kidney donors operated with hand-assisted retroperitoneoscopic donor nephrectomy (HARP)...
