RESUMO
Intraoperative ultrasound assisted localization is routinely used in the surgical treatment of completely endogenous renal cell tumor, however the localization and guidance ability of conventional ultrasound will decline to a certain extent for isoechoic renal tumor. A 62 years old female patient with right renal tumor was reported. The tumor diameter was about 2.3 cm× 1.7 cm, equivalent to the isoechoic of kidney. Laparoscopic partial nephrectomy was performed under the real-time guidance of contrast-enhanced ultrasound. The tumor was found to be lack of blood supply during the operation, and the tumor contour was clearly developed by contrast agent.The operation was successfully completed, and the pathological diagnosis was polycystic renal tumor with low malignant potential.The incisional margin was negative.The patient recovered well after operation without complications.No recurrence or metastasis was found after 6 months of follow-up.The renal function was good.
RESUMO
IgG4-related diseases have a low incidence and are easily misdiagnosed as tumors in clinical treatments. A 26-year-old male patient was admitted to the hospital because of a left adrenal tumor found in health examination for more than 5 months. The tumor in the left adrenal region could be seen from abdominal CT, and the retroperitoneal laparoscopic resection of the left adrenal tumor was performed. Postoperative pathology was consistent with IgG4-related diseases, and serum IgG4 was abnormally high. After 2 months’ follow-up, serum IgG4 returned to normal, and no special discomfort.
RESUMO
The incidence of solitary fibroma of seminal vesicle is low, and the source of seminal vesicle is rare. A 38-year-old patient was admitted to hospital because of intermittent gross hematuria for more than one month. Seminal vesicle space occupying lesions can be seen in pelvic MRI. Laparoscopic resection of right seminal vesicle tumor was performed, and the pathological diagnosis tended to solitary fibroma. During the 5-month follow-up, the symptoms of hematuria disappeared and no recurrence.
RESUMO
Objective To analyze the feasibility and safety in application of resectoscope combined with laparoscopy in the operation treatment of paraganglioma of urinary bladder.Methods 7 cases patients with paraganglioma of urinary bladder treated in our hospital from November 2014 to August 2018 were analyzed retrospectively.There were 5 males and 2 females,average age of 31.1 years (22-37 years),average body mass index was 22.3 kg/m2 (18.3-22.5 kg/m2).All the 7 cases patients complained of dizziness and palpitation after urination,average basal systolic blood pressure was 111.8 mmHg (97-124 mmHg),the average fluctuation of systolic blood pressure before and after urination was 64.9 mmHg(28-91 mmHg),the CT and cystoscopy prompt bladder tumor,the average diameter was 2.7 cm(2.1-3.5 cm).The average of plasma norepinephrine was 706.3 pg/ml(330-997 pg/ml);the average of plasma dopamine was 101.1 pg/ml(44-145 pg/ml);the average of 24h urinary vanilmandelic acid was 13.4 mg/24h (10.3-16.1 mg/24h).All the patients has controlled the blood pressure and dilate the blood vessels with phenoxybenzamine hydrochloride,accepted the operation of resectoscope combined with laparoscopy partial cystectomy and bladder sutura per abdomen after ample dilatancy.The patients had lithotomy position with trendelenburg,preparation of gas peritoneal cavity by transabdominal,inside the resectoscope by transurethral at the same time,mutilated bladder mucosa beside 1cm at the edge of the tumor,and cut full thickness bladder wall,take the extraperitional fat as the standard procedure;we could see the cutting edge clear at this time by laparoscopy,cut off the pelvic peritoneum,extraperitional fat and the tumor.The sample placed in bladder,close the bladder with absorbable or barbed wires,take out the sample by resectoscope.Results All the 7 cases patients operation was successfully completed,no cases has been transfered to open.The average time of operation is 85.3 min(65-100 min),the average amount of bleeding is 27.9 ml(10-50 ml).The average fluctuation of systolic blood pressure is 8.7 mmHg(6-15 mmHg).Bladder washout was stopped 24h after operation,catheter was removed 1 weeks after operation.There is no obvious complications occurred.The average hospital stay is 3.7 days (3-5 days).The average pain score of 4 cases 4h after operation is 3.8 (2-5),reevaluation 24h after operation is 2.3 (1-4).The average follow-up time is 7.9 months(2-15 months).All the 7 cases patients clinical symptoms disappeared,there is no fluctuation of systolic blood pressure before and after urination,there is no recurrence of the tumor.Conclusions To the paraganglioma of urinary bladder in fundus of bladder or anterior wall of bladder,we can accurate resection tumor by resectoscope combined with laparoscopy,reduce blood pressure fluctuations,reduce the surgical trauma and the distress of patients.It is a safety and effective minimally invasive surgery.
RESUMO
Objective To analyze the consistency of the detection results of glycosylated hemoglobin (HbA1c) by SMART POCT and Hitachi 7180 biochemical analyzers .Methods Firstly the accuracy of HbA1c detected by the SMART POCT and Hita‐chi 7180 biochemical analyzers were evaluated .And then 20 randomly selected samples were tested by both equipments .A relevance analysis between detected data from two equipments was conducted .Results There was a good correlation between the results of the HbA1c detected by two detecting systems ,with the correlation coefficient of r2 =0 .981 1 .Conclusion There is a good consis‐tency in detection results of glycosylated hemoglobin (HbA1c) detected by SM ART POCT and Hitachi 7180 biochemical analyzer .
RESUMO
Objective To study the efficacy and complications of reconstruction of failed urethro-plasty for hypospadias with pedicle flap , bladder mucosa , buccal mucosa , and biological patch . Methods 23 patients were enrolled from Jul .2005 to Dec.2011.8 patients, with good local skin condition , were performed with pedicle flap urethroplasty .The other 15 patients, with bad local skin condition or with long segment urethral stricture , were performed with free grafts , including 6 bladder mucosa , 7 buccal muco-sal and 2 biological patch. Results Of the 23 cases, 7 cases were cured by one phase operation .There were 16 (16/25) cases had complications.3 (3/16) cases were failed because of serious infection (2 pedi-cle flap, 1 bladder mucosa ) .The failed cases were implemented with urethroplasty 6 months later by the buccal mucosa installments operation .4 (4/16) cases had solitary urethral fistula (1 pedicle flap, 2 bladder mucosa, and 1 buccal mucosal), who were successfully treated with simple fistula repair 3 to 6 months later. 9 ( 9/16) cases had urethral stricture ( 2 pedicle flap , 3 bladder mucosa , 3 buccal mucosal , and 1 biologi-cal patch graft ) , who were treated with urethral sound and got good result .We had reconstructed the urethra using mucosa graft onlay urethroplasty .All of the 23 patients were followed up with an average of 14.5 ( 6-24) months.23 cases were satisfied with the stretched penis , urination and no need to expand the urethra more than 6 months.3 cases were not satisfied with penile appearance .After communication, these patients did not require a further penis orthopedic surgery . Conclusions Pedicle flap, bladder mucosa , buccal mucosa and biological patch can be used in urethral repair and construction of failed urethroplasty for hypos -padias.Urethral sound dilation plays an important role in hypospadias repair .
