EVALUATION OF THE INCIDENCE AND OUTCOME OF FETAL HYDRONEPHROSIS PRENATALLY DIAGNOSED BY ULTRASOUND

The outcome and proper management of fetal hydronephrosis have not been completely defined. The purpose of this study was to determine incidence and outcome of infants with a history of prenatal hydronephrosis diagnosed by ultrasound. In a three-year period from 2000 to 2003 we identified 211 cases (271 renal units) of fetal hydronephrosis in which renal pelvic anteroposterior diameter was more than normal diameter at various stages of pregnancy. Incidence of fetal hydronephrosis was 3.8 percent in the 55500 fetuses screened by ultrasound. A total of 187 fetuses (240 renal units) followed up underwent postnatal sonography and only in ten cases renal pelvic anteroposterior diameter was greater than 15 mm that required surgical correction . The most important advantage of knowing that a fetus has ultrasound findings of persistent hydronephrosis is ability to begin timely evaluation of the newborn to identify severity of hydronephrosis and prevent progressive deterioration of renal function

Hydronephrosis Due to Bilateral Tubo-ovarian Abscess

A 27-year-old female presented to the emergency department with fevers, nausea, chills, and non-specific bilateral lower quadrant abdominal pain. A pregnancy test was negative. Computed tomography demonstrated moderate left hydronephrosis secondary to tubo-ovarian abscess. The abscess was so large it distorted local anatomy and compressed the ureters. She was prescribed meropenem and admitted for care by obstetrics/gynecology

Concomitant CIS on TURBT does not impact oncological outcomes in patients treated with neoadjuvant or induction chemotherapy followed by radical cystectomy

© Springer-Verlag GmbH Germany, part of Springer Nature 2018Background: Cisplatin-based neoadjuvant chemotherapy (NAC) for muscle invasive bladder cancer improves all-cause and cancer specific survival. We aimed to evaluate whether the detection of carcinoma in situ (CIS) at the time of initial transurethral resection of bladder tumor (TURBT) has an oncological impact on the response to NAC prior to radical cystectomy. Patients and methods: Patients were identified retrospectively from 19 centers who received at least three cycles of NAC or induction chemotherapy for cT2-T4aN0-3M0 urothelial carcinoma of the bladder followed by radical cystectomy between 2000 and 2013. The primary and secondary outcomes were pathological response and overall survival, respectively. Multivariable analysis was performed to determine the independent predictive value of CIS on these outcomes. Results: Of 1213 patients included in the analysis, 21.8% had concomitant CIS. Baseline clinical and pathologic characteristics of the ‘CIS’ versus ‘no-CIS’ groups were similar. The pathological response did not differ between the two arms when response was defined as pT0N0 (17.9% with CIS vs 21.9% without CIS; p = 0.16) which may indicate that patients with CIS may be less sensitive to NAC or ≤ pT1N0 (42.8% with CIS vs 37.8% without CIS; p = 0.15). On Cox regression model for overall survival for the cN0 cohort, the presence of CIS was not associated with survival (HR 0.86 (95% CI 0.63–1.18; p = 0.35). The presence of LVI (HR 1.41, 95% CI 1.01–1.96; p = 0.04), hydronephrosis (HR 1.63, 95% CI 1.23–2.16; p = 0.001) and use of chemotherapy other than ddMVAC (HR 0.57, 95% CI 0.34–0.94; p = 0.03) were associated with shorter overall survival. For the whole cohort, the presence of CIS was also not associated with survival (HR 1.05 (95% CI 0.82–1.35; p = 0.70). Conclusion: In this multicenter, real-world cohort, CIS status at TURBT did not affect pathologic response to neoadjuvant or induction chemotherapy. This study is limited by its retrospective nature as well as variability in chemotherapy regimens and surveillance regimens.Peer reviewedFinal Accepted Versio

Advanced chondrosarcoma of the pelvis: a rare case of urinary obstruction

Chondrosarcoma is the second most common malignant tumor of the bone with an incidence of 1 in 200.000 per year. Axial skeleton is frequently involved showing poorer oncological outcomes than appendicular one: human pelvis is a site predilection. It is rarely associated to urinary obstruction but according to its localization, it can be frequently linked to compression of pelvic organs as bladder, prostate or bowel. We describe the case of a 52 years old caucasian male with history of advanced pelvic chondrosarcoma and severe hydronephrosis due to total bladder dislocation

Primary Renal Lymphoma Presenting as End-Stage Renal Disease.

Primary renal lymphoma is a rare entity, even more so in children. Children with primary renal lymphoma present with variable clinical features such as constitutional signs and symptoms, acute kidney injury, palpable abdominal masses, and gross hematuria. Herein we report a child who presented with seemingly advanced chronic kidney disease and was eventually diagnosed with primary lymphoma. He responded well to intensive chemotherapy and recovered renal function, although he was left with some functional limitations as a consequence of his treatment regimen. Our report highlights the importance of keeping neoplastic conditions under consideration when taking care of children with severe kidney disease of unclear etiology

Congenital imperforate hymen with hydrocolpos and hydronephrosis associated with severe hydramnios and increase of maternal ovarian steroidogenic enzymes

This is a clinical research paperStudy Objective: To study clinical features of patient presented with severe hydramnios, associated with hydronephrosis, that was antenatally diagnosed and has been successfully treated immediately after birth. At a molecular level, we investigated the gene expression of key steroidogenic enzymes from the maternal ovary. Design: Ultrasound scan,MRI, semi-quantitativeRT-PCR Setting: The patient was admitted to the University Hospital, University of Crete, Medical School, Greece, where all clinical data has been obtained. Gene expression studies took place at Biosciences, Brunel University, UK. Results: Semi-quantitative RT-PCR analyses revealed that there is upregulation of key steroidogenic genes in the maternal ovary, including steroidogenic acute regulatory protein, and the cytochrome P450 heme-containing proteins CYP11A, CYP17 and CYP19. From a clinical perspective, the prenatal ultrasound scan and MRI findings showed a multicystic pelvic mass, bilateral hydronephrosis and prior to delivery severe polyhydramnios. Conclusion: This clinical case is the only one that we have found in the current literature where congenital imperforate hymen accompanied with hematocolpos is associated with renal obstruction in combination with polyhydramnios and increase in maternal steroidogenic enzymes

A novel detrimental homozygous mutation in the WFS1 gene in two sisters from nonconsanguineous parents with untreated diabetes insipidus

Given the limited lifespan and with the recent progress in experimental treatments for WS, timely diagnosis and multidisciplinary treatment for DI/DM, hydronephrosis, and visual/psychiatric status-maintaining quality of life-are of crucial importance

The menstruating bladder, an unusual cause of haematuria

A 39 year old lady presented with flank pain and haematuria. Radiological investigations showed unilateral hydronephrosis and a serum creatinine of 102?mol/l. At cystoscopy, a soft tissue mass was found in the region of the left ureteric orifice and was causing obstruction of the ureter. A resection biopsy of this lesion was taken. A CT scan and DTPA renogram showed a non-functioning left kidney secondary to chronic obstruction by a soft tissue mass at the left vesico-ureteric junction. Histological analysis of the endoscopic resection specimen showed that the mass contained tubal-type epithelium compatible with a diagnosis of endosalpingiosis (a rare variant of Mullerianosis of the urinary tract). In view of persistent symptoms, it was decided to proceed to surgery. A hysterectomy, bilateral salpingo-oophorectomy and partial cystectomy were performed. The patient has recovered well and is currently asymptomatic. Formal histology of the resection specimen showed the presence of endometriosis.peer-reviewe

A brief review of the literature on the malignant ureteral obstruction

Malignant ureteral obstruction (MUO) caused by a primarily urological tumor or secondary to a late-stage malignancy can be difficult for the urologist to manage. Due to a lack of clinical data on the management of MUO, every case is particular and should be aborted individually. Lack of specific treatment, either palliative or definitive, can severely damage renal function and lifetime expectancy in patients, causing even more damage that could otherwise be avoided. Prompt management directed at the recovery of renal function is the main goal in such cases. Even after urinary flow is restored, life threatening post-obstructive diuresis needs to be managed
