3D model facilitated zero-ischaemia laparoscopic nephron sparing resection in nephroblastomatosis following the addition of cis-retinoic acid
There are limited reports of laparoscopic nephron sparing surgery (LNSS) in children and none where a 3D model facilitated oncological resection. There are also limited reports discussing the use of cis-retinoic acid in bilateral diffuse hyperplastic peri-lobar nephrogenic rests(DHPLNR).We report the first case of a 3D model facilitated zero-ischaemia LNSS in children and the first following treatment with cis-retinoic acid.The patient was a 3-year-old girl with bilateral DHPLNR who had recurrent disease following standard therapy.
Gretzer et al.1 describe a patient with symptomatic benign prostatic enlargement (BPE) who underwent prostatic urethral lift (PUL) and subsequently developed ecchymosis with computed tomography (CT) showing bilateral pelvic hematomas. This case is the first published incident of pelvic hematoma after PUL and was presumably self-limiting and required no further intervention.
Impact of CYP2D6 polymorphisms on tamoxifen treatment in patients with retroperitoneal fibrosis: A first step towards tailored therapy?
To investigate the influence of CYP2D6 polymorphisms on outcomes and health-related quality of life (HRQoL) of patients with retroperitoneal fibrosis (RPF) receiving tamoxifen (TMX). TMX is an effective alternative to corticosteroids for patients with RPF. Conversion of tamoxifen to more potent endoxifen is dependent on enzyme activity of CYP2D6.
Don´t Forget Burkitt´s Lymphoma! Unusual Case of Primary Malignant Lymphoma of the Prostate in a Young Patient
Primary Burkitt´s lymphoma of the prostate is rare in the adolescent population. The etiology remains poorly understood. There´s been some proposed associations to Epstein-Barr virus and HIV. Clinical and histopathological data of a 17-year-old patient who underwent transurethral resection of the prostate was obtained. We report the first case of primary malignant BL of the prostate in a 17-year-old Caucasian male who presented with hematuria, lower urinary tract symptoms. Differential diagnosis of a prostatic mass in adolescent patients must be primary or secondary lymphoma of the prostate, including BL as described for the first time in this article.
Herniation of the right renal pelvis through a posterolateral diaphragmatic defect (Bochdalek hernia)
Diaphragmatic herniations are the rarest form of ureteral herniations with only around 9 cases reported since 1958.1-10 Though uncommon, it should be considered in the differential diagnosis of a posterior diaphragmatic or paraspinal opacity with associated hydronephrosis. Correct diagnosis is of paramount importance and can be easily established by non-invasive imaging technique. In symptomatic individuals, laparoscopic intervention can be offered with good results in fit patients with ureteral stenting reserved for poor surgical candidates .Here we present a successful laparoscopic management of an elderly female who presented with right flank pain and was diagnosed with a right sided diaphragmatic ureteral herniation.
Thank you for sharing your interesting case. As referenced in our initial article, previous studies have noted that the most frequent complications experienced following the UroLift procedure are dysuria, hematuria, pelvic pain, urgency, and urinary tract infections1,2,3. Although patient results following the procedure are positive, with the L.I.F.T trial reporting a significant improvement in patient IPSS score with durable results 5 years post-operatively4, we have noted the potential for other complications not described in these clinical trials.
HIGH-VOLUME CONCURRENT POLYPOID URETERITIS AND URETERITIS CYSTICA MANIFESTING WITH URETERAL OBSTRUCTION
Polypoid ureteritis, or fibroepithelial ureteral polyps, are a rare but benign neoplasm of unknown etiology in the upper urinary tract and may occur at any age. 1 Ureteritis cystica is also a rare but benign phenomenon that may develop following inflammatory conditions of the ureter and/or renal pelvis.1 Due to their appearance on imaging and frequently accompanying symptoms of gross hematuria, the masses are often clinically indistinguishable from upper tract urothelial carcinoma (UTUC) in adults.
Reviewing historical evidence indicates that the history of urinary stones is probably associated with the history of civilization.1,2 There are archeological reports on urolithiasis occurrence in the preserved mummies dating from 7000 years ago.2 Physicians of ancient civilizations were familiar with the etiology, clinical manifestations, and treatments of urinary tract diseases, e.g. urinary stones. In this regard, many studies have reviewed the history of urolithiasis1-3 and some of them considered the concept of urinary tract diseases in medieval Persian medicine (PM).

Onabotulinumtoxina Re-Injection for Refractory Detrusor Overactivity Using 3-4 Injection Sites: Results of A Pilot Study

Shockwave Lithotripsy Use in the State of Michigan: American Urological Association Guideline Adherence and Clinical Implications
To understand how treatment of patients with urinary stones by shockwave lithotripsy (SWL) aligns with current published practice guidelines.
Dablaca-11: Photodynamic Diagnosis in Flexible Cystoscopy – A Randomised Study with Focus on Recurrence.
To examine whether Photodynamic diagnosis (PDD) in addition to flexible cystoscopy in the outpatient clinic can reduce risk of tumour recurrence in patients with previous non-muscle invasive bladder cancer (NMIBC). PDD is an optical technique that enhances the visibility of pathological tissue and helps guidance tumour resection.
Risk Factors for Upstaging, Recurrence, and Mortality in Clinical T1-2 Renal Cell Carcinoma Patients Upstaged to pT3a Disease: an International Analysis Utilizing the 8th Edition of the Tumor-Node-Metastasis Staging Criteria
To investigate risk factors for and outcomes in pathological T3a-upstaging in Renal Cell Carcinoma (RCC), as Tumor-Node-Metastasis staging for T3a RCC was recently revised.
Prostate cancer non-ascitic peritoneal carcinomatosis after robot-assisted laparoscopic radical prostatectomy: three case reports and review of the literature
Robot-assisted laparoscopic radical prostatectomy (RALRP) is one of the treatment options for localized prostate cancer, with an excellent disease control rate. However, these patients can experience late disease recurrence with metastatic dissemination. Peritoneal metastases are an uncommon recurrence site. Here, we discuss three cases of peritoneal metastases following RALRP and the mechanisms of peritoneal invasion. Through a literature review and our case reports, we postulate the existence of two distinct mechanisms of peritoneal invasion: one being iatrogenic, following a laparoscopic surgery with a well differentiated prostate cancer at a non-advanced stage of the disease, the other involving the natural course of poor-prognosis tumours, even without surgery.
The history of urolithiasis on Earth began during the stone age (Mesolithic period) with the oldest stone identified (8,500 BCE) in Sicily within the bladder of a cave-dwelling woman.1 The history of stone disease has continued throughout human evolution with calculi being found in both the kidney and the bladder in ancient Homo sapiens.2 Hippocrates (460-370 BCE) recognized stone disease in society and included within the current Hippocratic oath, “I shall not cut for stone,” thus illustrating that urolithiasis is genuinely an ancient disease.
A 34 year-old female with Stage V chronic kidney disease secondary to a history of sickle cell anemia and focal segmental glomerulosclerosis and on peritoneal dialysis presented to our hospital for imaging as part of routine evaluation for renal transplant. Upon receiving an MRI of the abdomen to evaluate liver architecture and kidney anatomy, a 6.6 cm left perinephric mass was incidentally found inferomedial to the left kidney and extending caudally (Figure 1). The renal parenchyma and ureter were uninvolved.

To perform an updated literature review to assess compliance with outcomes use and reporting guidelines. In 1997, the Urodynamics Society recommended standards of efficacy to be used for evaluation of treatment outcomes in urinary incontinence (UI). Studies published shortly after the release of these standards reported generally low rates of adherence.
