Ureterorenoscopy (URS) is a minimally invasive treatment option for removal of kidney stones, which has gained importance in this field over the past two decades. This technique has replaced extracorporeal shock wave lithotripsy (ESWL) stone surgery for many indications. It is also particularly important in the diagnostics and treatment for tumors of the upper urinary tract. This article describes the indications, surgical technique and management of complications of URS. [ABSTRACT FROM AUTHOR]

Ureteral obstruction represents a heterogeneous disease pattern and is treated by ureteral stenting or percutaneous nephrostomy (PCN) depending on the necessity. The benefits of urinary diversion with ureteral stenting or PCN in malignant ureteral obstruction (MUO) for patient survival are only moderate. No differences have been found between ureteral stenting and PCN in MUO with regard to median patient survival and complication rates. In cases of MUO there is currently no evidence that urinary diversion improves the quality of life. Alternative concepts of ureteral stenting, such as tandem ureteral stents, metallic ureteral stents or metal mesh ureteral stents have not yet shown clear benefits. In benign ureteral obstruction, prospective randomized studies have demonstrated comparable quality of life after PCN or ureteral stenting. The method of choice for urinary diversion is influenced by the recommendations, personal experience of the clinician and the availability of the method. [ABSTRACT FROM AUTHOR]

Background: Purpose of this work is to compare the outcome of ureterorenoscopy (URS) with regard to stone-free rates (SFR) and complication rates (CR) in patients with different body mass index (BMI) scores for the treatment of kidney stones.Materials and Methods: A retrospective chart review of all patients with known BMI, who underwent URS for kidney stones between 2006 and 2012 at our institution, was performed (n = 556 patients). The SFR and CR of obese patients were compared to overweight and normal weight patients.Results: Mean age was 52.51 years and the average BMI 27.74 kg/m2. Of the patients, 34.2 % had normal weight (22.59 ± 1.91 kg/m2), 39.6 % were overweight (27.30 ± 1.42 kg/m2), and 26.3 % were obese (35.09 ± 5.93 kg/m2). The mean ASA score differed significantly between normal weight (1.99 ± 0.57), overweight (2.03 ± 0.62), and obese (2.22 ± 0.63) patients (p ≤ 0.036). The mean stone size was 8.51 ± 6.84 mm and the mean number of stones per patient 1.9 ± 2.41, whereby the differences between groups was not significant. There were no differences between the groups regarding the use of preoperative (94.8 %) and postoperative ureteral stents (60.3 %), the Ho:YAG laser (33.6 %), the use of flexible (16.2 %) or semirigid/flexible URS (59.4 %), and the mean operative time (52.04 ± 34.55 min). There were no differences in the SFR for the upper (90 %), mid (94.7 %), and lower pole (90.2 %), multiple location (68.6 %) or the total SFR (86.3 %). Total SFR of 95.7, 88.4, and 73.7 % for urinary calculi < 5 mm, 5-9 mm, and ≥ 10 mm, respectively, were found and the differences between the patient groups was not significant. The CR was 10.4 % (differences between the patient groups not significant).Conclusion: URS is an appropriate treatment for renal stones with high SFR and low CR regardless of patient's BMI.

Percutaneous nephrolithotomy (PCNL) is a well-established minimally invasive treatment option for removal of kidney stones. This technique has now replaced open stone surgery for virtually all indications. This article describes the indications, the surgical technique and the complication management of PCNL.

Endothelial cysts of the adrenal gland are a rare entity of adolescents. We here present the case of a 19-year-old woman, who developed right abdominal pain after trauma. Magnetic resonance imaging showed a tumor in the right adrenal gland with suspicious signs for malignancy. Histopathological examination revealed the diagnosis of an endothelial (vascular) adrenal cyst. In most cases, cysts of the adrenal gland remain clinically inapparent. In cases of clinically manifest symptoms, surgical intervention represents the standard for therapy. [ABSTRACT FROM AUTHOR]

Background: Numerous studies have shown that thulium vapoenucleation of the prostate (ThuVEP) is a size-independent minimally invasive procedure for the treatment of benign prostatic enlargement. All ThuVEP series have been performed with a 2-µm thulium laser device so far. The aim of this study was to evaluate the complications and early postoperative results of two thulium-devices with different wavelengths for ThuVEP in prostates larger than 80 ml.Materials and Methods: A retrospective bi-centric matched-paired analysis with 296 patients was performed. Based on prostate size, 148 were matched at each centre and laser device, respectively. A 2-µm (RevoLix, LISA Laser products, Katlenburg, Germany n=148) and a 1.9-µm (vela XL, starmedtec, Starnberg, Germany, n=148) thulium laser with a power output of 90 and 80 W was used. Patients' data were assessed and compared.Results: The median prostate volume (interquartile) was 100 ml (range 86.25-120 ml). At discharge, Qmax (preoperative 7.9 and 9 ml/s vs. postoperative 19.35 and 16.2 ml/s) and postvoiding-residual urine (preoperative 130 and 45 ml vs. postoperative 20 and 25 ml) were significantly improved after 2-µm and 1.9-µm ThuVEP (p<0.001). The median catheterization time and hospitalization times were 2 and 4 days in both groups. Perioperative complications occurred in 89 patients (30.1%): Clavien 1 (12.2%), Clavien 2 (9.1%), Clavien 3a (0.7%), Clavien 3b (7.1%), and Clavien 4a (1%). Regarding the occurrence of complications, there were no differences between the two thulium devices.Conclusion: ThuVEP represents a safe and effective treatment for prostates larger than 80 ml. Both thulium laser devices give satisfactory immediate micturition improvement with low perioperative morbidity. [ABSTRACT FROM AUTHOR]

After circumcision, a young man developed a wound healing disorder. After presenting to our hospital for further wound care, laboratory results showed acute renal failure with hemolytic anemia and thrombocytopenia, which led to the diagnosis of postoperative thrombotic thrombocytopenic purpura (TTP). After therapy with plasma exchange and immunosuppressive therapy with prednisolone and rituximab, the patient recovered with normalization of laboratory results. The TTP is associated with low activity of ADAMTS13 with microvascular platelet aggregation and hemolytic anemia. [ABSTRACT FROM AUTHOR]

The natural course of untreated, asymptomatic calyceal calculi has not yet been clearly defined regarding disease progression and risk of surgical interventions. The decision for an active treatment of calyceal calculi is based on stone composition, stone size and symptoms. Extracorporeal shockwave lithotripsy (ESWL) has a low complication rate and is recommended by the current guidelines of the German (DGU) and European (EAU) Associations of Urology as a first-line therapy for the treatment of calyceal stones <2 cm in diameter. However, immediate removal of stones is not achieved with ESWL. The primary stone-free rates (SFR) after ESWL depend on stone location and stone composition and can show remarkable differences. Minimally invasive procedures, such as percutaneous nephrolitholapaxy and ureteroscopy are alternatives for the treatment of calyceal stones which have low morbidity and high primary SFR when performed in centres of excellence.

A pneumoscrotum due to long-term ventilation is a rare entity. We present the case of a 59-year-old man with adult respiratory distress syndrome (ARDS) and long-term ventilation, who required intensive care and had severe subcutaneous emphysema and a pneumoscrotum. Computed tomography revealed subcutaneous emphysema of the neck, chest, and abdomen, emphysema of the mediastinum, a pneumoperitoneum, pneumoretroperitoneum, and pneumoperineum. A puncture of the scrotum confirmed the diagnosis of a pneumoscrotum. The patient died in the course of progressive ARDS. [ABSTRACT FROM AUTHOR]
