Salvage prostate intensity modulated radiation therapy after cryotherapy failure.

Cryotherapy is an ablative therapy that can be used to treat localized prostate cancer. In case of recurrence, treatment options are not well-defined, and their outcomes are unknown. We therefore collected all patients treated with radiotherapy after cryotherapy for prostate cancer recurrence in Nantes (France) between 2012 and 2019.

Management of testicular cancer: Practice survey in localized stage.

Introduction: Management of testicular cancer requires a complete evaluation to confirm the localized stage and effective treatment according to guidelines to ensure the best outcome. The primary objective of this study was to evaluate practices at each stage of care in patients with a localized testicular tumor. The secondary objective was to evaluate the oncological prognosis of these patients according to the modalities of care.

Roadside vehicle particulate matter concentration estimation using artificial neural network model in Addis Ababa, Ethiopia.

Currently, vehicle-related particulate matter is the main determinant air pollution in the urban environment. This study was designed to investigate the level of fine (PM) and coarse particle (PM) concentration of roadside vehicles in Addis Ababa, the capital city of Ethiopia using artificial neural network model. To train, test and validate the model, the traffic volume, weather data and particulate matter concentrations were collected from 15 different sites in the city.

Localized chromophobe carcinomas treated by nephron-sparing surgery have excellent oncologic outcomes.

Objective: To evaluate the oncologic outcomes of nephron-sparing surgery (NSS) for localized chromophobe renal cell carcinoma (cRCC).

Material And Methods: We performed a multicenter international study involving the French Network for Research on Kidney Cancer (UroCCR) and 5 international teams. Data from 808 patients treated with NSS between 2004 and 2014 for non-clear cell RCCs were analyzed.

The subclassification of papillary renal cell carcinoma does not affect oncological outcomes after nephron sparing surgery.

Objectives: To evaluate the oncological outcomes of papillary renal cell carcinoma (pRCC) following nephron sparing surgery (NSS) and to determine whether the subclassification type of pRCC could be a prognostic factor for recurrence, progression, and specific death.

Materials And Methods: An international multicentre retrospective study involving 19 institutions and the French network for research on kidney cancer was conducted after IRB approval. We analyzed data of all patients with pRCC who were treated by NSS between 2004 and 2014.

The upper limit of the tumour thrombus was below the hepatic veins in 21 cases (52.

[Unusual metastatic spread after converted laparoscopic radical nephrectomy: natural history of the tumour or role of laparoscopy?].

Retroperitoneal or transperitoneal laparoscopic radical nephrectomy is currently proposed by an increasing number of urologists as an alternative to conventional open surgery to treat renal tumours. The authors report a case of metastasis to unusual sites (sigmoid colon, small intestine, root of the nose) after converted retroperitoneal laparoscopic radical nephrectomy for a T3 renal tumour, which raises the problem of the possible role of the laparoscopic approach in this unusual metastatic progression of the disease.

[Therapeutic management of ureteric strictures in renal transplantation].

Objective: Ureteric strictures, with a reported incidence ranging from 2% to 7.5%, are the most frequent urological complication of renal transplantation. This article reports the results of open surgery and percutaneous or endoscopic techniques used to treat these strictures, based on a single-centre retrospective series of renal transplantations.

[Predisposing factors for ureteric strictures in renal transplantation].

Objective: Renal transplantation is a well defined surgical procedure, but it nevertheless remains associated with a risk of medical and surgical complications. Ureteric strictures, with an incidence ranging from 2% to 7.5% according to the series, are the most frequent urological complication.

[Small round cell desmoplastic tumour presenting as a testicular mass].

The authors report a case of small round cell desmoplastic tumour presenting as a testicular mass. This is a rare tumour arising from serosal tissues, especially the tunica vaginalis. It is characterized by a specific reciprocal translocation t(11;22) (p13;q12) inducing fusion of the EWS and WT1 genes.

Objective: The objective of this retrospective study was to evaluate the mortality and early and late morbidities of Bricker ileal conduit urinary diversion.

Patients And Methods: Between January 1990 and December 2002, 246 Bricker ileal conduit urinary diversion was performed in our centre in 164 males (67%) and 82 females (33%) with a mean age of 64 years (range: 9 to 90 years). Bricker diversion was performed in 73.

[Retrospective study of laparoscopic retroperitoneal radical nephrectomy].

Objective: To analyse the results of laparoscopic retroperitoneal radical nephrectomy in terms of feasibility, morbidity and disease control.

Patients And Methods: Between October 1997 and May 2004, 42 laparoscopic retroperitoneal radical nephrectomies were performed in 33 men and 9 women for renal tumour. Three or four trocars were used depending on the operative findings in order to achieve oncological imperatives: primary control of the renal pedicle before mobilization of the kidney (the artery was clipped and the vein was sectioned by Endo-GIA), passage in the plane of radical nephrectomy and absence of direct contact with the tumour The operative specimen was extracted whole in an impermeable endoscopic bag by enlarging a trocar orifice to avoid any parietal contact.

[Ureteric catheter nephrostomy: simple and effective drainage after percutaneous nephrolithotomy].

The authors describe an original technique of postoperative drainage of percutaneous nephrolithotomy consisting of leaving a 5 F ureteric catheter in place, which descends into the bladder and drains into a conventional 18 or 20 F nephrostomy drain. It ensures ureteric drainage while eliminating the need for a urethral catheter, protects the nephrostomy tunnel by maintaining the nephrostomy drain in place and maintains access to the caliceal group used for percutaneous nephrolithotomy.

[Management of radiation cystitis].

Radiation cystitis is a lesion of the bladder caused by irradiation of a pelvic organ. These lesions can range from a simple inflammatory reaction to almost complete bladder retraction. The frequency of chronic lesions is estimated to be between 5% and 10% of patients receiving pelvic radiotherapy.

[Renal hydatid cyst: preoperative diagnosis and therapeutic implications].

Renal hydatid disease is a rare condition in temperate climates, but must be diagnosed. The authors describe the systematic radiological and serological assessment for a renal cystic mass establishing a preoperative diagnosis. On the basis of this preoperative diagnosis, essential precautions can be taken to avoid the specific complications of this disease and a nephron-sparing procedure can be performed.

[Ventriculo-ureteric shunt without associated nephrectomy for the treatment of hydrocephalus].

The authors report the case of a 51-year-old patient with hydrocephalus following posterior fossa surgery (cerebellar astrocytoma) treated by ventriculo-peritoneal shunt, then ventriculo-atrial shunt. After repeated valve revisions (diffuse peritoneal loculation, intracardiac thrombus responsible for dyspnoea and recurrent pulmonary embolism, shunt infections), another mode of shunting was required. The authors opted for ventriculo-ureteric shunt comprising ureteric reimplantation into a psoas bladder, without associated nephrectomy, which appears to constitute an alternative in the case of difficult surgical management of hydrocephalus or after failure of other modes of ventricular shunting.

[Mixed epithelial and stromal tumour of the kidney].

The authors report the case of a patient with mixed epithelial and stromal tumour, a rare, recently described entity, as only 40 cases have been reported, mixed epithelial and stromal tumours are essentially observed in women during the perimenopausal period with a history of treatment with oestrogen-progestogens or gynaecological surgery. No clinical or radiological arguments can differentiate these tumours from other renal tumours. Histological examination reveals a tumour with an epithelial component and a stromal component presenting the characteristics of ovarian stroma and expressing oestrogen and progesterone receptors.
