Ureteral stent related symptoms: A comparative study.

Background: In urology, ureteral stents are used to treat obstructive diseases. Hematuria (54%), fever, discomfort, and lower urinary system symptoms are the predominant symptoms related to ureteral stent.

Aim: This article links stent symptoms to double-j width and length, as well as patient's height, weight, and body mass index (BMI).

Ureteral Stent-Related Symptoms and Pharmacotherapy: A Brief Narrative Review.

The purpose of this article is to review the effects of different types of pharmacotherapy on symptoms that affect the quality of a patient's life after stent insertion. A thorough Medline/PubMed nonsystematic review was conducted from 1987 to January 2023, using the terms: "pigtail" OR "ureteral stents" AND "lower urinary tracts symptoms" OR "LUTS" AND "pharmacotherapy" OR "drugs". Relevant studies conducted in humans and reported in English language were included.

The role of imaging in the management of renal masses.

The wide availability of cross-sectional imaging is responsible for the increased detection of small, usually asymptomatic renal masses. More than 50 % of renal cell carcinomas (RCCs) represent incidental findings on noninvasive imaging. Multimodality imaging, including conventional US, contrast-enhanced US (CEUS), CT and multiparametric MRI (mpMRI) is pivotal in diagnosing and characterizing a renal mass, but also provides information regarding its prognosis, therapeutic management, and follow-up.

Numerical simulation modeling of the irreversible electroporation treatment zone for focal therapy of prostate cancer, correlation with whole-mount pathology and T2-weighted MRI sequences.

Background: At present, it is not possible to predict the ablation zone volume following irreversible electroporation (IRE) for prostate cancer (PCa). This study aimed to determine the necessary electrical field threshold to ablate human prostate tissue with IRE.

Methods: In this prospective multicenter trial, patients with localized PCa were treated with IRE 4 weeks before their scheduled radical prostatectomy.

Materials And Methods: Two groups of 50 patients each underwent nerve-sparing RRP for localized prostate cancer by one surgeon. In one group, the vesicourethral anastomosis was performed using 2 Vicryl 2-0 stitches placed at the 3- and 9-o'clock positions and in the other group 6 Vicryl 2-0 stitches were placed at the 2-, 4-, 6-, 8-, 10- and 12-o'clock positions.

Percutaneous renal cryoablation: current status.

Over the last 13 years, renal cryoablation has emerged as a promising technique for the treatment of solid renal tumors. The improvement in imaging modalities such as ultrasound, computed tomography and MRI, as well as the introduction of thinner probes, has led to the spread of the minimally invasive percutaneous approach. We review the historical background of percutaneous renal cryoablation (PRC), present its basic principles, mention the contemporary clinical data and outcomes of this technique and suggest future directions for its wider application in renal tumors.

Ureteroscopic removal of mildly migrated stents using local anesthesia only.

Purpose: In the outpatient office setting we evaluated the feasibility and efficacy of ureteroscopic removal of upward migrated ureteral stents using local or no anesthesia.

Materials And Methods: Prospectively 37 patients with mild upward stent migration underwent ureteroscopic stent removal under local or no anesthesia. Stent migration was always below the pelvic brim.

Pathological review of internal genitalia after anterior exenteration for bladder cancer in women. Evaluating risk factors for female organ involvement.

To evaluate cancer involvement of internal female genitalia of patients undergoing anterior exenteration for clinically organ confined transitional cell carcinoma of the bladder, and identify potential preoperative risk factors. Charts and anterior exenteration specimens from 54 women with clinically organ confined transitional cell bladder cancer were retrospectively reviewed. Emphasis was given to the presence of internal genitalia involvement and or primary gynecologic pathology.

Primary retroperitoneal teratoma presenting as an adrenal tumor in an adult.

Primary teratomas in the retroperitoneum are rare in adults. Most teratomas in this region are secondary to germ cell tumors of the testes or ovaries. We describe a case of mature cystic teratoma that was clinically suggestive of an adrenal myelolipoma.

Objectives: To evaluate the effect of alfuzosin in improving symptoms in, and quality of life of, patients with indwelling double-J ureteral stents.

Methods: A total of 100 patients, 50 men and 50 women (mean age 54.2 years), with unilateral ureteral stone-related hydronephrosis, who had opted for conservative management with insertion of a double-J ureteral stent, were prospectively randomized into two groups.

Pain control requirements for percutaneous ablation of renal tumors: cryoablation versus radiofrequency ablation--initial observations.

Experience with laparoscopic renal/adrenal surgery in patients on chronic warfarin is limited. We assessed hemorrhagic/thromboembolic complications in this group of patients.

Small cell carcinoma of epididymis: multimodal therapy.

Extrapulmonary small cell carcinoma is an infrequent tumor that can occur in various organs. Although a few sporadic reports about extrapulmonary small cell carcinoma have been published, much remains to be uncovered about the clinical features, optimal treatment, and natural history. We present a case of small cell carcinoma of the epididymis with retroperitoneal recurrence, an exceedingly rare tumor with behavior and treatment not well characterized.
